Linear thrust unit: mount to valve
1.
Check whether attachment of linear thrust unit suit the valve.
2.
Push thrust rod of linear thrust unit to desired position (e.g. OPEN) using the
handwheel.
➥
Assemble valve and actuator in the same end position.
➥
For globe valves, the conventional assembly position is end position CLOSED
(thrust rod is retracted).
3.
Clean mounting surfaces (mounting flanges at linear thrust unit and valve).
Thoroughly degrease uncoated mounting surfaces.
4.
Place linear thrust unit onto valve as to ensure that bores or thread align with
the mounting flanges.
Information: Ensure that the spigot fits uniformly in the recess and that the
mounting faces are in complete contact.
5.
Fasten linear thrust unit with screws and lock washers according to table.
Information: We recommend applying liquid thread sealing material to the
screws to avoid contact corrosion.
6.
Fasten screws crosswise to a torque according to table.
