Valve with stainless steel handwheel and pneumatic safety function

Product information

Diaphragm valve GEMÜ 650TL is a manually operated diaphragm valve with a pneumatic fail safe function. The valve can only be operated manually (opened/closed) if the actuator is supplied with compressed air. If this supply is interrupted, the valve closes due to the force of the spring and can no longer be opened manually.

Key features

  • Fail safe function (closed)
  • Proximity switches can be fitted for recording the valve position
  • CIP/SIP capable
  • Closing stroke limiter (MG 8)
  • Opening and closing stroke limiter (MG 10 + 25)
