Product Description
Pressure Vacuum valve / Flame Arrester meet the requirement of normal vent capacity. Emergency Pressure Relief Valve - Hinged Operated is required in every big, above ground storage tanks to protects them against fire in adjoining area. As per API 2000 standard, Hinged Operated Emergency Pressure Relief Valve must be used to meet the relief requirements. If this valve is not used, the fire near the storage tank with flammable liquid can transmit the heat through the tank walls and cause quick vaporization, high pressure inside the tank and at last a blast. This condition can be prevented by installing emergency pressure relief valve.

Description :-


The PRECON Model No: PFCI/EPRV/2051 valve is a hinged operated pressure relief valve ideal for application that demand a high flow capacity. It is mainly used in process equipment, process vessels, silos and other equipment. It protects the equipment from excessive overpressure. The spring loaded, hinged type or weight loaded emergency vent valve provides tight seal in normal conditions. It opens on the attainment of set pressure, it is when it releases the excessive vapour generated.
