22. Screw hexagon nut T onto the threaded part of the nozzle stem R and tighten with a torque

of 20 Nm while holding the control lever.

23.

Screw sealing plug O together with gasket N into the valve body and tighten with a torque of

130 Nm or screw in the sample valve with the gasket according to the instructions given by the

manufacturer.

24.

Put coupling 8 onto control lever U and ﬁx the mounting bracket 5 and actuator 1 to the valve

body using the hexagon screws 7. Adjust control lever until the coupling makes contact.

25.

Align the actuator, making sure that the coupling 8 is level on the control lever. Fasten hexagon

screws 7 with a torque of 7 Nm.

26.

Adjust the switching cams for OPEN, CLOSED and OPERATING POSITION or, if ﬁtted, the feedback

potentiometer according to the attached installation manual “Actuators EF...”.

27.

Set the switching cam for CLOSED in the actuator such that the torque checking pin 6 is to the

right but does not touch the checking hole.The closing torque in this position is 10 Nm. Fig. 13

All torques indicated in the table are based on a room temperature of 20 °C.
