Beswick Engineering's RVD series miniature diaphragm style
relief valve is a normally closed
valve, which opens on rising upstream pressure. The
valve will crack open (first bubble) at the specified
relief pressure, and continue to open further as overpressure increases. The
valve will then close again when upstream pressure drops below the set pressure (typically
1-2 psi below). Features and Specifications: The frictionless diaphragm design offers compactness, light weight and high accuracy...
