PS - Pressure-sustaining/ Relief Valve

The air pressure controlled PS - Pressure-sustaining/ Relief Valve maintains a steady, predetermined pressure in the network, upstream of its location. If the pressure falls below the set pressure, the valve closes drip-tight. This is a simplified and more reliable alternative to a spring-loaded relief valve.
