Series 26-04/03
Externally controlled and forced pilot operated valve.
In the rest position, the valve is closed by spring and medium pressure. The actuator pressurised with pilot pressure opens a pilot bore and lifts the piston from the main seat directly or assisted by the pressure difference. Valves of this design can also be supplied with the function opened by spring force. There is also a double-acting piston actuator.
