Pilot valve Valve Block
The externally controlled valve is pneumatically operated. It consists of a diaphragm actuator and a 2-way valve body. Between the valve housing and the drive, there is a hermetically sealed membrane.
The diaphragm actuator moves a spindle with valve disc against a spring and switches the valve. The spindle is designed glandless with double seal. The actuator body is made out of epoxy resin.
Circuit function A
2/2-way valve, externally controlled, normally closed by spring operation with pilot valve
Circuit Function B
2/2-way valve, externally controlled, normally opened by spring, operation with pilot valve
