Servo-controlled solenoid valve NC, DN 25

14.025.126 series water inlet valves are 2/2-way solenoid valves with an orifice size of 25 mm. They have been developed to control potable water and physically and chemically similar media. They are servo-controlled and normally closed (NC).

Valves of this design are single chamber straight through valves and can be manufactured with various connections equipped with metal female threads.
Coil systems for common voltage and frequency ranges are available.

Electrical operating safety is achieved by insulation class F and can be supported by an integrated protective circuit.

By using high quality insulation materials, continuous operation (duty cycle 100 %) is possible. Protection against corrosion of inner parts exposed to the medium is achieved by using stainless steel.
