Flow Control DivisionKammer Control Valves3.4.3 Unscrew the coupling insert until the yoke rods areraised from the lower yoke plate by around 2 mm.Attention: Ensure that the plug assembly is notrotated with the plug seated. This may causeirreparable damage to the seating faces.3.4.4 Refit the coupling, ensuring that the arrows,embossed on the coupling halves, point upwardtowards the actuator, and secure with 2 retainingscrews.4.2 Assemble Valve(see Fig. 2)4.2.1 All worn or damaged parts must be replaced. Reusableparts must be clean. Expendable parts such asgaskets, packing and O-rings should always be replaced.4.2.2 Insert seat ring and tighten. For torques, see followingtable:Size Body Torquematerial3.4.5 Apply supply pressure resp. vent actuator to half strokeand refit and tighten yoke rod retaining nuts (15).3.4.6 Connect all tubing.4 DISASSEMBLE AND ASSEMBLE VALVE4.1 Disassemble Valve(see Fig. 2)4.1.1 Remove bonnet flange bolting and raise bonnet andplug assembly.Caution: heavy assemblies may require a hoist4.1.2 Unscrew seat ring using seat ring tool and carefullypress plug stem evenly out of the upper body.4.1.3 With valves DN 80 / kv 63 and larger, the plug headcan be unscrewed (see Fig. 3). Remove plug headfrom stem by securing valve stem against rotationwith a hooked spanner and turning plug head withan adjustable face pin tool.4.1.3 Check seating faces of seat ring and plug for damage.Gasket surfaces must be clean and free of damage.4.1.4 Press guides, packing and packing follower frombelow using a drift (the drift must have a slightlylarger diameter than the plug stem).Important: To prevent damage to the plug or plugstem, follow the above instructions precisely.4.1.5 If a seat surfaces need re-machining, seat and plugseating surfaces must be reworked. The seat angleon the plug is 30°, on the seat ring 25°. If the valve iscorrectly assembled, lapping is not required.Important: When re-machining the plug, protectplug stem from damage. The seat surface must beconcentric to the plug stem. When re-finishing theseat, the seat surface must be concentric to the seatouter diameter.DN 15/25 ( 1 /2 /1") 1.4581 cast 125 Nm1.4571 forged 125 NmDN 40/50 (1 1 /2 /2") 1.4581 200 Nm1.4571 255 NmDN 80 (3") 1.4581 230 Nm1.4571 270 NmDN 100 (4") 1.4581 400 Nm1.4571 500 NmDN 150 (6") 1.4581 450 Nm1.4571 600 Nm4.2.3 If necessary, screw plug head back on to stem andcarefully guide plug stem through the bonnet, to avoiddamage.4.2.4 Insert new bonnet gasket.4.2.5 Position bonnet slowly and absolutely upright onbody, to avoid damage to seat/plug.4.2.6 Tighten bonnet flange bolts alternating crosswise finger-tightand then tighten with a wrench.
