General Information

Complete fitting, consisting of ball cock and pneumatic actuator.

Robust and compact construction.

Maintenance-free actuator with control piston and coarse thread.

The lifting of the piston is converted into a rotation of 90° +3° due to the coarse thread.

Actuator made of plastics, therefore excellent corrosion resistance as well as high weight savings compared to conventional metal designs.

High torque performance, high efficiency factor as well as high flow rates even at heavily contaminated media.

The actuator has a stable plastic housing made of glass fibre reinforced PP with high surface hardness and best stiffness.

The unit consisting of ball cock and actuator is available in the following designs:

Type A: double acting (the rotation of the ball occurs exclusively with compressed air).

Type B: single acting (SA) with spring return, normally open (NO). The cock position changes from “open" to “closed" by the actuator applying compressed air. The resetting to the starting position is effected by means of elastic force.

Type C: single acting (SA) with spring return, normally closed (NC). The cock position changes from “closed" to “open" by the actuator applying compressed air. The resetting to the starting position is effected by means of elastic force.

Control of the cock is possible with all neutral, gaseous media.

The bottom end on the pneumatic actuator serves for connection of the control pipe, the top end serves for air vent.

All connections are designed as G-internal thread, thus allowing numerous and easy adaption possibilities.

The system is compatible to THOMAFLUID®-/ MULTIFIT®- tubing connectors EMP-3 (parts 20246) or pipe connectors EMP-4 (parts 10642).
