Safety Relief Valve

Salient Feature

USMANI Valves co Pvt. Ltd. Safety/Pressure Relief Valves are manufactured with high accuracy to assure the performance of the valve, protect very critical & expensive equipment’s from dangerously high pressure. It is knowledgeably design, manufactured & tested for Zero Defect.

Safety valves and relief valves are so designed so that the disc lifts automatically when the inner pressure rises to a set pressure, and then closes when the pressure level drops to a predetermined value.

Safety valves and relief valves protect various equipment from overpressure and are deemed essential for this reason. We have been manufacturing various specialized valves, including the main steam relief valve (SRV) for nuclear power plants and the power control valve (PCV) for thermal power plants.
