BAKER CONTROL VALVES - Premier Valves

2BAKER CONTROL VALVESControl ValvesTHE BAKER VALVE “INSIDE STORY”As a control valve that has been in the South African market since1975 and that has always been well respected as one of the topplayers, BAKER is on a new mission to recapture the all importantcontrol valve market in South Africa. Now manufactured andmarketed by Premier Valves, BAKER is ready to set new standards inautomatic self actuated control valve technology. Following are someof the existing features and benefits of the BAKER control valve:• Larger flow passages with resultant greater capacities.• Greater cavitation resistance - 4:1 allowable pressure drop.• “Quad” Seal which provides a bubble tight closure and long lifewith reduced maintenance.As the only completely South African owned and manufacturedcontrol valve design the BAKER is currently available in pressurerating up to 50 bar and size range from 50mm to 600mm. A largetest rig at Premier’s premises enable development work to makeBAKER “state of the art” with features customised for South Africanconditions. Designs are on the drawing board for 150 bar valves forthe SA Goldmines.ServiceBoth pre-sales and after sales services are crucial to the successof control valves. It is Premier’s mission to provide the best in boththese areas.Pre-sales serviceBecause so many factors need to be considered in correct selectionof control valves, staff and agent training has high priority toensure that the customer gets the right advice and ensure long andtrouble-free operation. To this end regular training programs areheld at Premier’s premises with an emphasis on both theoreticaland practical training on the test rig. Premier have for many yearssupplied complete Pressure Reducing stations up to 150 bar workingpressure where correct operation and safety features are importantto ensure safe and continuous water supply.Training programs arealso available for customers.

BAKER CONTROL VALVES3FeaturesFusion Bonded Epoxy Prolongs LifeThis coating is applied under rigorous preparation andapplication standards. It is non-porous, improving the flowco-efficiency of the valve and effectively sealing the castingfrom interaction with the controlled liquid. The coatingalso protects the valve from environmental attack. Thefinish prevents mineral build-up and rust (a major factor incontrol valve failure), simplifies maintenance, and prolongsthe life of the valve.Standard coating thickness: 250 microns.Other coatings available on request.Superior PerformanceThe design and innovative features incorporated intoevery Baker Automatic Control valve meansconsistent, dependable, high performance, positivecontrol and long life.Efficient DesignThe main valve is diaphragm actuated, hydraulicallyoperated. It consists of only four major components.The body and cover plus interior seat anddiaphragm/stem assembly, which is the only movingpart in the main valve.Variable Volume Cover ChamberA synthetic rubber/nylon diaphragm, of reinforcedBuna N materials, is assembled between the valvebody and cover. This creates a sealed chamber intowhich line fluid and pressure is introduced. Varyingthe amount of pressure accurately positions the stemassembly to open, close or modulate the valve asrequired.Precise Alignment And Stable ThrottlingA cover bearing and integral seat bearing guides thestem assembly for precise alignment with the seat.Coupled with the quad seal retainer plate, thisalignment assures progressive opening/closing flows,stable throttling, low friction operation and positiveclosure.Drip Tight SealBaker leads the automatic valve industry by beingthe first to incorporate the dynamic quad seal.The seat is retained on three ½ sides and iscompletely out of the flow path. It provides positiveclosure while eliminating the need to “bite” into theseal, adding years to the valve’s live. Each quad sealhas two usable sides. The Quad Seal has been in usefor many years and has reduced maintenance by aconsiderable amount.A P.O.

6BAKER CONTROL VALVESPower ChamberPOWER CHAMBER HYDRAULIC CONTROL VALVE (AVAILABLE AS OPTIONAL FEATURE)Power Chamber Feature On/OffAlthough this can be used for modulating control, the mostcommon use for the power chamber is to permit the valve toopen when the supply pressure is low. The valve bias spring isomitted in this arrangement and it is essential that the valve issupplied with slow closing speed control to prevent waterhammer. The most usual applications for the Power Chamberare in Level control when residual pressure is very low and inPump Control to ensure the valve goes fully open and minimiseenergy consumption.Supply pressure is fed both under the valve seat and under thediaphragm via a 3-way pilot to the lower diaphragm chamber.This provides relatively large valve opening forces even at lowpressure. To close, the supply pressure is switched to the upperdiaphragm chamber.A secondary advantage of the Power Chamber is that thediaphragm is protected from damage caused by particles in theflow stream.The CV value of the Power Chamber Valve is slightly larger than thestandard valve because the seat no longer has an integral bearing.A P.O.

BAKER CONTROL VALVES7Level Control OverviewThe Baker valve can be used to control Water Level inReservoirs and Tanks in a variety of different ways dependingon many factors such as Pressure and Flow conditions andconfigurations of the installation. A logical way to classify thedifferent methods to control level is by On-off or Modulation.Within both groups an almost unlimited combination of otherfunctions can be added such as Pressure Sustaining, rate ofFlow control, Solenoid override etc, which makes the BakerControl valve very versatile. In both groups the choice can bemade to install the valve as a top-of-reservoir valve mountedinside (or outside) the reservoir, or as a bottom entry with thevalve mounted on the bottom of the reservoir. Please note thata stilling well should be installed with the float pilot if waterturbulence could affect the operation. The stilling well can be anappropriate diameter plastic pipe (normally 200mm).Hydraulic ConditionsIn order for Level control valves to operate effectively andprovide long trouble-free life, flow and pressure conditionshave to be investigated. Two pressure conditions can createproblems i.e.1) High PressureDam (or reservoir) control valves have always been susceptible totwo potential problems caused by high pressure conditions whichcan be overcome if one is aware of what the problems are.CavitationMost control valves can handle a pressure drop ratio of no morethan 3:1. Because of it’s unique features the Baker control valvecan handle a 4:1 pressure drop ratio. Even so in a Level controlapplication if one assumes a back pressure of 1 bar from thehead of the reservoir downstream of the valve, the valve can onlyeffectively cope with 4barupstream in order to provide a long life.High Flow RatesIf a level control valve is allowed to go fully open and dynamichead is above 1.5bar, a flow rate far beyond the recommendedcan occur which can cause further damage. In both of the abovesituations the extent of the valve’s life will be determined by thelevel of the upstream pressure. If the discharge into the dam isfree with the valve installed at the end of the line, the problem isnot as severe because cavitation will occur outside the valve, butone still has the high velocity problem.Our recommendations for these installations are outlined below.· Upstream Dynamic head between 5 and 10 barInstall a Flow control pilot on the Baker Level Control Valve tolimit flow rate to an acceptable level and install an orifice platedownstream of the valve to provide an artificial back pressure.The valve will still experience cavitation during the opening andclosing cycles, but as long as the cycles are not too frequentand closing and opening speed is not too long, the aboverecommendations should ensure a reasonable valve life.· Upstream Dynamic head over 10 barInstall a Flow control pilot on the Baker Level Valve and install anadditional Pressure Reducing valve upstream of the Level controlvalve. The Pressure Reducing valve can be either a pilot operatedBaker valve or a Premier Ratio Reducing valve which operateswithout a pilot and can handle pressure drops of up to 5:1.2) Low PressureFlowing line pressure should be 50kPa or more to ensure thatsufficient head is available to open the valve fully. This assumesthere is not pressure in the control chamber. The other factor tobe aware of is that with the valve at the bottom of the reservoirand the float pilot at the top, the static head in the control tubingis the minimum pressure which can be achieved in the controlchamber with the normal pilot hook-up. A “rule of thumb”which can be used to check this condition is as follows:The flowing line pressure in PSI should be greater than or equalto the vertical distance in feet between the valve and the floatpilot.A P.O.

The pressure set point isadjustable within the spring range. Up stream pressureis sensed under the diaphragm. As upstream pressureincreases, the diaphragm pushes against the spring. The pilotstem/seat is pulled toward the open position, increasing flowthrough the pilot. As upstream pressure decreases underthe diaphragm, the spring pushes the stem/seat toward theclosed position restricting flow through the pilot. This sensitivespring/diaphragm interaction closely tacks and responds tochanges in upstream pressure.START-UP/ADJUSTMENTFollow the start-up procedure for theBaker function you have selected.1. Turn the screw Clockwise (IN)to increase the set-point you arecontrolling.2.

22BAKER CONTROL VALVESEngineering Data / SizingINSTALLATION RECOMMENDATIONS AND REQUIREMENTSVertical InstallationsAvoid mounting valves 6” and largerin a vertical discharge position (valvestem horizontal or cover pointedsideways). If our installation requiresthis mounting position consult thefactory or specify at time of order.Valve Sizing - Pressure ReducingSelection of the correct size pressure reducing valve is a relatively simpleprocess. Criteria for selection are a minimum flow, normal flow, maximumflow and pressure drop across the valve. Following are explanations of thethree types of PRV installations. These also apply to any functions combinedwith the reducing function, such as reducing/check and reducing /solenoidvalves. A Relief valve should be installed downstream for dead-end service.Isolation Shut-Off ValvesButterfly or similar type valves should be installed in the line upstreamand downstream of the automatic control valve to allow for maintenanceservice. Installing an isolation valve will allow you to performmaintenance service without draining the system or exposing servicepersonnel to line pressure.Single Valve InstallationA single reducing valve can be applied if operating flow, requirements arewithin the capacity of one size valve, and pressure drops are outside theCavitation Zone.1. Select the valve size from SIZING CHART that is within the range of lowto high flow. (Consider requirements of lowest demand equipment).2. Check Pressure Drop (inlet-outlet) to insure that desired outlet pressureis above the recommended lowest outlet setting to avoid cavitationconditions. (Check Cavitation Chart page 21).SPECIAL CONSIDERATIONSFloat Valves• Installing valves over open tanks should be avoided dueto possible servicing problems.• Install stilling wells around floats to protect them from turbulence.• Remote mounted float controls should be connected to the main valvewith a minimum of 3/8” tubing.Solenoid Valves• Electrical wiring should conform to NEMA codes to assure proper valveoperation and longevity.Rate Of Flow Valves• A butterfly isolation valve cannot be installed directly to the valve inletflange, as the disc will contact the orifice plate. A gate or ball type valvecan be used or the isolation valve can be installed further upstream.Parallel InstallationIf flow requirement fall outside the capacity of a single valve, an additionalsmaller valve installed in parallel may be required. In parallel installations,the larger valve handles the requirements for maximum flow down to itslow flow capacity. The small valve extends to the sum of the maximum flowof both valves.1. Select the valve size combinations from SIZING CHART thatis within low to high flow system range.2. Check Pressure Drop (inlet-outlet) to confirm desired outletpressure is above index psig, or check Cavitation Chart.Altitude Valves• Install the valve as close to the tank as possible, a maximum of 40 pipediameters to assure accurate control.• A sense line is required to connect the altitude control to the tank. Toprovide accurate reading of head pressure, the line should connect atthe base of the water column. Minimum sense line size is ½”. A shutoffvalve should be installed in this line for service and start-up.Series InstallationIf pressure drop requirements cause the outlet pressure to be below theindex psig, or fall in the Cavitation Zone, then two valves in series maybe required. Each valve will function outside the cavitation zone to safelydrop the high inlet pressure, in two steps, to the desired outlet pressure.Valve size is based upon the Minimum - Maximum flow ranges previouslyexplained. Consult Baker representative for these applications.A P.O. Box 11735, Randhart, South Africa, 1457 W www.premiervalves.comT +2711-908-3760 F +2711-864-2525 E sales@premiervalves.com

24BAKER CONTROL VALVESValve SizingTo properly size an automatic control valve you need to know thefollowing:• Minimum flow requirements'• Maximum flow requirements'• Outlet pressure• Highest and lowest inlet pressure1. Utilize the high flow chart and select the flow as found on the horizontalaxis which corresponds with your maximum flow requirements.2. From this point draw a vertical line until you intersect with thehorizontal line corresponding with the minimum differential pressure.(Your minimum differential pressure will be the lowest inlet pressureminus the desired outlet pressure this is also know as the delta P).3. From this point move right to the first valve size line. This will be theMinimum valve size which should be used on intermittent flow of 7.6m/s. If maximum flow is continuous, then do not exceed the l/s (6m/s)listed on the maximum continuous flow table.4. Utilize the flow chart and select the maximum differential pressure asfound on the vertical axis. (The maximum rP will be the highest inletpressure minus the desired outlet pressure).5. From this point draw a horizontal line until you intersect with the linecorresponding to the valve size as selected in step 3.6. From this point draw a vertical line down to the horizontal axis.This will be the minimum flow capability of the valve based on thesevariables.a) If the minimum flow capability obtained from step 6 is above youractual minimum flow requirements, you should consider a parallelinstallation. Using the minimum flow capability, begin at step 1 toselect the size you will need for this low-flow bypass.b) Use the cavitation chart and determine if the intersection of theinlet and outlet pressures falls in the shaded area. If so, you shouldconsider a series installation. Both valves should be sized inaccordance with the above steps.A P.O.
