2/2 Normally Open - Pressure Assisted

2/2-way normally open solenoid valves that use the pressure difference between inlet and outlet to assist operation. These valves allow flow when de-energised and close when power is applied, provided the specified operating conditions are met. A minimum pressure differential is required, commonly 0.5 bar, although this varies by model. Choose brass, stainless steel or plastic bodies, with WRAS-approved options on selected water valves. Check media and seal compatibility, flow capacity, temperature, supply voltage and the available pressure differential throughout operation. Our technical team can help you select a suitable valve.
