2/2 Normally Closed - Zero Rated

2/2-way normally closed, zero-rated solenoid valves for on/off flow control without a minimum pressure differential. These valves open when energised and close when electrical power is removed, making them suitable for systems with low or variable inlet pressure. Choose from direct-acting and assisted-lift designs in brass, stainless steel and plastic, with selected WRAS approved water valves and specialist gas, steam and high-pressure models. Vacuum suitability depends on the individual valve. Match the pressure rating, flow capacity, seal material and coil voltage to your application, or contact our technical team for selection advice.
