Introduction Detailed description This regulator is a diaphragm sensing spring loaded back-pressure regulator, designed to regulate low pressures at medium gaseous flow. The back-pressure regulator keeps control of the inletpressure. If the inletpressure exceeds the setpressure, the valve opens and gas starts to flow. It is ideal for highly accurate control of pressure because of it’s large effective sensing area.
