Construction
The GEMU CleanStar®C60 / C67 HPW ultra pure pneumatically or manually operated 3/5 way diaphragm valves have a full PFA-HP body with two valve seats. All medium wetted parts are in PFA-HP or PTFE (diaphragm). The non-wetted bonnet is PVDF. The standard version of type C60 (pneumatic) is designed as a diverter valve: 1 x NC and 1 x NO (2 pneumatic actuators C60, one normally closed, one normally open). C60 has a stroke limiter and an optical position indicator (1), C67 (manual) has a travel stop (6) as standard. Solid mounting lugs (2) are integrated and there is also a connection for a leakage detection sensor (3). The union nuts can be either in PVDF-HP or PFA-HP (4). C67 has a standard optical position indicator (5).

Advantages
  • Proven actuator reliability
  • High Purity Design
  • High Cv values
  • Bi-directional flow
  • Can be used as a media blending valve
  • Actuators can be independently controlled
  • Can be fully integrated with existing GEMU process controls
