IMPORTANT:
The lift dimension is measured between the upper surface of the lift stop (10) and the guide
upper surface using a depth gauge. For valves with restricted lifts, the actual lift will be the value which is
stamped on the nameplate and in the computerized sizing report.
• Adjust the lift stop (10) with one hand whilst with the other hand prevent the spindle from turning
thus stopping the disc (11) from turning on the seat.
• To lock, screw down the lift stop in order the first notch faces the pin hole.
• Insert and open the cotter pin (89). The cotter pin "head" must be in the horizontal position to ensure
that the end of the pin will not touch the cover whilst the spindle being subjected to lift.
• Screw down the overlap ring (28) so that the external grooves are slightly below the level of the pin
hole.
• Take off the yoke assembly (3)
• Screw down the four cover studs (35) using nominal torque
• Assemble the cover (2) on the body (1) by inserting from the top of the spindle (13).
• Tighten the cover nuts (60) using nominal torque on to the cover studs.
