RG4 control valves
Continuous control of flow and pressure. Diaphragm actuator and positioner as standard.
REF · CONTROL
Modular control
Swap the stem and seat when the required Kvs changes — without replacing the whole valve.
- Aseptic versions: PTFE diaphragm, bellows or steam barrier (RGMS4).
- Low-noise version.
