Pneumatic diaphragm valve DIASTAR Six
The perfect solution when it comes to an economical valve with compact dimensions and a long life cycle. This actuator has been optimised especially for elastomer diaphragms and 6 bar working pressure.
Fail-safe-to-close (FC mode)
In the non-operative state, the valve is closed with spring force. When the actuator is pressurised with the control medium (bottom connection), the valve opens. When the control medium escapes, the valve is closed via spring force.
