Carbon Steel Spring Load Open Type Full Bore Pressure Relief Safety Valve With Lever
Product introduction:
A safety valve is a pressure reducing or removing device. It guards against overpressure in a system. It opens very quickly. It opens at a certain pressure, it does so gradually before opening completely to eliminate undesired pressure from the system as rapidly as feasible. It stops the buildup of pressure that could cause malfunctions, fire risks, or explosions. In the event of a power outage, a safety valve is maintained in operation by the system’s media. When electronic or pneumatic safety devices malfunction, safety valves, which only have mechanical parts, are activated. If the pressure inside a system or vessel is higher than the safe threshold, both the facility and the workers could suffer devastating consequences. These valves are made to automatically release liquid or gas pressure from any system that has pressure, preventing excessive pressure and safeguarding equipment and people. It needs to be correctly sized, chosen, installed, and maintained in order to fulfill all of these requirements.

Product features:
• Safety valve normally with spring-loaded type, Pilot-operated type, deadweight type, balanced type for thermal, steam and pressure adjustment.
• Safety valves prevent equipment from being damaged due to overpressure or vacuum conditions. They automatically open and relieve excess pressure, preventing costly damage to the equipment.
• Safety valves protect personnel from harm caused by explosions or sudden release of hazardous materials due to overpressure and help to increase productivity by preventing unplanned downtime and reducing equipment failure rates.
• Safety valve widely used in chemical industry, oil and gas industry, petrochemical industry, air conditioning industry, energy industry, aircraft hydraulic industry and irrigation system etc, also in pressure vessels, pipelines, process equipment and transportation fields.
