The 5212 series pilot-operated safety relief valves are mainly used in the fields of oil and gas, chemical industry, electric power, metallurgy, and natural gas. It is the best overpressure protection device for pressurized equipment, containers, or pipelines. The allowed working pressure is close to the set pressure of the safety valve. A small overpressure can quickly make the main valve reach the full opening state. This safety valve’s operating performance and opening height are not affected by back pressure.
