The force-controlled 2/2-way solenoid valve has a metal piston sealing element that is equipped with an ring-shaped seat seal made of elastomer. The E24 to DN100 variant is characterised by two PTFE piston rings, which makes it particularly suitable for applications with water (H₂O). Optionally, the valve can be equipped with a position monitoring for the positions ‘OPEN’ and/or ‘CLOSED’. Force-controlled valves combine the advantages of servo-controlled and direct-controlled models. They do not require a pressure difference for the opening process and are excellently suited as automatic shut-off devices for larger nominal diameters.
