11.  Service Instructions

17. 

Screw in the stop screw (26) until it stops.  

 

 

Tightening torque Md = 10 Nm

The stop screw must be flush with the top of the piston.

18. 

Fasten the adapter on the actuator with the 4 screws.

19. 

Screw the operating cam on the guide rod (7).

11.4.   Installation of the valve insert 

1. 

Carefully place the valve insert in the valve housing (1) until the 

screw stops.

2. 

Remove the jacking screw and carefully press the valve insert into 

the housing (1). 

3. 

Screw in the hex. screws (30) and fasten them crosswise. 

4. 

Place the control unit on the adapter. Make sure that the control unit 

is centered on the adapter.

5. 

Place the clamp ring and fasten it with the screws.

6. 

Assemble the compressed air lines.

Air connection 1: 

to open valve

Air connection 2:  

to lift upper shaft

Air connection 3: 

to lift lower shaft

7. 

Check the valve position indicators 

Closed valve position feedback – sensor 1 controlled

To adjust Hall sensor 1, ensure that the valve is in the closed 

position, the solenoid / manual override are not activated. Turn 

adjustment screw 3 into the required position. The LED "Valve 

Closed" lights up.

Open valve position feedback – sensor 2 controlled

To adjust Hall sensor 2, first activate the solenoid valve 1, either 

manually or electrically. Then turn adjustment screw 1, to adjust 

the open valve position and the corresponding feedback. When it 

reaches the required position, the LED “Valve Open” lights up.

Observe the switching hysteresis of the Hall effect sensors! 

Therefore, adjust the switch point of the sensors with overlap in 

order to permit small variations. We recommend additional 2 x 360° 

turns of the adjustment screw. 

8. 

Design with proximity switch holder:  

 

 

 

Set the proximity switch holder in position and fasten it with 

the screws. Check to see if the “Valve Closed” or “Valve Open” 

message appears. Re-position the proximity switch if required.
