7.1 Valve mounting for cut-off by force at extended actuator stem
Initial position: Valve stem is retracted, actuator stem is extended.
1.
Put actuator onto the bracket.
2.
Remove the coupling pin and screw the coupling 13 mm on the valve stem. There must be a 1 mm gap between
the pillars and the bracket.
3.
Insert the spring clamp with the coupling pin again and fix the locking nut.
4.
Connect the actuator to electric supply (see 9.).
5.
Retract the actuator spindle manually (see 10.6) until the edges of the pillars rest on the bracket.
6.
Screw and tighten the pillar nuts.
7.2 Valve mounting for cut-off by force at retracted actuator stem
Initial position: Valve stem is extended, actuator stem is retracted.
1.
Remove the spring clamp with the coupling pin and screw the coupling 13 mm on the valve stem.
2.
Put actuator onto the bracket, make sure actuator stem is immersed into the coupling. Screw on and fix the pillar
nuts.
3.
Connect the actuator to electric supply (see chapter 9.), either electrically or with the handwheel and drive the
actuator manually (see chapter 10.6) until the spring clam with the coupling pin is ready to be re-inserted.
RIGHT
WRONG
Before the pillar nuts are tightened, make sure
that the pillars are sitting on the valve mounting
bracket. If necessary, correct the position of the
actuator by using manual operation. If these
instructions are not observed, personal injury or
damage to the actuator and/or valve may result.
