Sanitary valves Pneumatic actuators
Double-acting: Ventilation on, ventilation off
Single-acting gas-opening type: ventilation open, air cut-off, gas source failure closed
Single-acting gas-closed type: ventilation closed, air cut-off open, gas source fault open
Optional accessories: Reversing solenoid valve, limit switch, air filter pressure reducing valve, electric positioner, handwheel mechanism, position retaining valve
Sanitary valves Working principle
Sanitary valves can be driven by electric or pneumatic actuator, with signal to automatic control the valve open and close. The actuators rotate the discs freely within 90° to open or close or regulate the flow of the medium.
Sanitary valves Leakage Class
Soft sealing butterfly valve: Zero leakage
Metal hard seal concentric butterfly valve: 1% leakage
Metal hard seal double/triple eccentric butterfly valve: Zero leakage
