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...

Hosco Fittings, LLC, Livonia, MI, has introduced the new Hosco BPV-150 Mechanical Pressure Relief Valve that relieves paint and solvent circulating system pressure in the event of system over-pressurization. This cavity-free and silicone-free valve can replace expensive "rupture disk" or conventional relief valves. As opposed to the rupture disk system the Hosco valve opens and closes automatically when required and will not shut down and halt production. Conventional pressure relief valves...

valves regulate return flow to tank, and the EPFR provides excess flow unloading. Flow not required by the cylinder is vented to tank at load pressure (plus spring value) rather than relief valve pressure, improving system efficiency and reducing heat. The RV08-29 relief valve is used to set maximum system operating pressure. When the valve setting is reached, pilot flow is vented allowing the EPFR to bypass pump flow to tank. The small RV08-29 is used in place of a separate high-flow relief... (read more)Browse Hydraulic Valves Datasheets for HydraForce, Inc.
