Solenoid Valves (NPP)

For the highest requirements - tested, qualified, long-lasting

For more than 45 years, we have been manufacturing direct-controlled solenoid valves for worldwide, demanding applications in nuclear power plants. In the delivery of components in high-sensitive nuclear power plants, it is not done alone with their delivery. Our strength besides the production and testing of our solenoid valves, is their qualification, the required documentation and the successful acceptance by the customer.

Available nominal widths: DN 8 - DN 50
Possible operating pressures up to 20 bar directly controlled, up to 78 bar internally pre-controlled
Housing materials: Stainless steel (to customer specification), stainless steel, PP, PVDF
Sealing materials: EPDM, FEP, FKM, FKM-F, PTFE, pure metallic
