The actuators and automation components from GEMÜ mean that even the most demanding control functions can be implemented.
Globe valves are the best control valves because of their seat design and long stroke. Dependent on the area of application and the type of control required other valves such as diaphragm valves, butterfly valves or ball valves can be used for control tasks.
GEMÜ globe valves are paired with regulating cones and positioners or process controllers, the standard control characteristics are equal-percentage, 1:25 and 1:50. As all components are from a single source they are well synchronised with each other and easy to commission. Control valves can be used in all industrial areas.

Pneumatic or motorised
The pneumatically operated valves are ideally paired with the GEMÜ 1434, 1435 or 1436 positioners. Motorised control valves can be supplied with an integrated positioner.

- T valve (3/2-way valve)
Other types of GEMÜ control valves
Long-stroke globe valves are particularly well suited to control tasks, however, for some applications, other valve types are more suitable for the process. Examples of this would be for fibrous or abrasive media. For these, a diaphragm valve might be a good possible alternative. GEMÜ actuators and controllers can therefore be adapted to different butterfly, ball and diaphragm valve bodies.
