2/2 Normally Open - Zero Rated

2/2-way normally open, zero-rated solenoid valves for applications requiring operation from zero pressure differential. These valves remain open when de-energised and close when electrical power is applied. Choose from brass, stainless steel and plastic bodies for compatible liquids and gases, with specialist options for steam, vacuum and high-pressure duties. Zero-rated operation requires no minimum pressure difference between inlet and outlet; vacuum suitability depends on the individual model. Match the valve’s pressure rating, seal material, flow capacity and coil voltage to your application, or contact our technical team for advice.
