automatic control valve 

Automatic self-acting control valve SERIES EU100 

Automatic self-acting control valve designed for regulating water flow in water pipelines, such 

as: waterworks, irrigation, fire-fighting, process plants, etc. The main functions performed by 

the valve (also valve combinations) are as follows: - shut-off-check-reduction, stabilization of 

the pressure-relief, overpressure-pressure support-level control-flow control. 

The more advanced models are equipped with a central control unit (EU900), of AISI 303 

stainless steel construction, which allows the regulating action to be performed as required by 

setting the flow opening and closing speeds as well as the response gradient to the deviations. 

The pilot devices serve for determining the type of function and the set-point of the parameter 

under control. All valves are provided with visual indication of the valve plug stem position.

FUNCTIONS 

The self-acting valves of Series EU100 consist of a main two-way 

body of globe type Fig 1, whose flow section is controlled by a 

shaped plug actuated by the energy supplied by the flow under 

control through a diaphragm inserted between the body and cover to 

form the operating chamber. When a small quantity of the fluid flows 

through the water control circuit, this circuit places the following ports 

in communication with each other : 

- upstream port with pressure generally higher 

- downstream port with pressure generally lower 

- port of the operating chamber with regulated intermediate pressure. 

An adjustable throttle is installed at the outlet of the upstream port, 

and before communication with the operating chamber. The pilot 

device is installed at the inlet of the downstream port. When the pilot 

device is fully open Fig 2 it allows direct discharge of the operating 

fluid coming from the upstream port; this causes a drop in pressure 

due to the throttling and determines a low level of pressure in the 

operating chamber and discharge of the latter.

The valve plug is raised to full opening position, thrust by the fluid 

under control. The fully closed pilot device Fig 3 causes the same 

high pressure present on upstream side to be present in the 

operating chamber (throttling with zero flow does not cause drops) 

and determines the fluid under control to be shut-off. When the pilot 

device is in intermediate position Fig 4 it allows partial discharge of 

the operating fluid coming from the upstream port; this produces a 

proportional drop in pressure due to the throttling and determines, in 

the operating chamber, an intermediate level of pressure and volu 

me. Hence the valve plug modulates the lifting of the valve plug (in 

opening or in closing) thus ensuring that the required levels of flow 

or pressure are reached.

Self-acting diphragm valve EU115-UR 

Self-acting diapraghm valve serving to reduce and stabilize the downstream pressure. With 

regulator unit EU900. The higher, upstream pressure is adjusted, on downstream side, to a 

lower and constant level even in the presence of upstream overpressure and / or variations in 

flow rate. Version with needle valves. Adjustment range of pilot device: Standard: 1,4 - 12,0 

bar. On request: 0,1 - 2,0 bar, 7,0 - 21,0 bar (stainless steel version). The additional non-return 

function is available On request (EU115-3).

Self-acting diapraghm valve serving to hold the downstream pressure at a constant and adjustable 

level. When the level of upstream pressure tends to decrease, it is held by gradually 

reducing the flow rate; instead when the downstream pressure level tends to increase, it is held 

by gradually increasing the flow rate at the outlet (relief or overpressure function). Version with 

needle valves. Adjustment range of pilot device: standard: 1,4 - 12,0 bar. 

On request: 0,1 - 2,0 bar, 7,0 - 21,0 bar (stainless steel version).

Self-acting diapraghm valve serving to control the flow rate passing the valve at a constant 

and settable value: normally the maximum acceptable drawing off value is held. The flow rate 

is monitored continuously through a calibrated flange located upstream of the valve, whose 

piezometric sockets are connected to the special pilot device which also allows setting with a 

differential pressure gauge. Version with needle valves. Obviously the available flow rate range 

(see table below) depends on the DN and calibrated flange; therefore it should be stated when 

ordering. Range of differential pressure adjustment with standard pilot device: 0,2 - 1 bar.

UNI 9182 standard cites: "All hot and cold water distribution systems must be provided with water hammer arrestors of 

hydropneumatic type (with permanent or resettable air cushions)." Each model of the CAW series is able to offer a certain 

cushioning action (table 1); hence for facilitating the choice we have given a table (table 2) with the unit load values 

assigned to each shut-off component (or units) normally installed in plumbing and hot water systems. 

N.B. Install the water hammer arrestor as close as possible to the shut-off component causing the water hammer.

Compact thermostatic mixing valve MMV-C 

Compact thermostatic mixing valve designed to supply general purpose applications with 

tempered water not exceeding a set temperature. Ideal for multi-facility applications: domestic 

homes, schools, restaurants, laboratories, motorway services, commercial buildings... anywhere 

needing a supply of water at a temperature pre-set on site. Rapid fail safe if cold water 

supply is interrupted (comply with EN1111 and with BS1415 Pt 2 - TMV2). 

1/2” or 3/4” Male/Male union threaded on inlets and outlets or compression fitting 15 or 22 mm. 

Pressure at the valve inlets must be within the 5:1 ratio under flow conditions. The size and 

layout of pipework and in-line fittings must take this into consideration. Optimum performance 

achieved with equal pressure. Temperature: accurate to within 1,5°C of chosen temperature 

(with balanced dynamic pressure). Head loss under dynamic presure at the mixer inlets is 

shown by the curve. Maximum static pressure: 10 bar. Operating pressure: 0,2 to 5 bar. 

Hot temperature supply: 52* - 85°C, *differential minimum hot/mix temperature must be 10°C. 

Cold temperature supply: 5 - 20°C. Temperature setting range: 30 to 65°C. Factory temperature 

setting: 36°C. Flow rate at 3 bar: 57 l/min. Flow mini: 5 l/min. Body strenght: 25 bar.
