Use
This newly designed pilot-operated safety relief valve is primarily used in the petroleum and natural gas, chemical, electric power, metallurgical, and city gas industries. It provides overpressure protection for pressure equipment, vessels, and pipelines. The design changes the direct action of the spring to indirect actuation through a guide valve, improving operating sensitivity. The main valve uses a sleeve piston and is characterized by high operating precision, good repeatability, high reseating pressure, zero leakage, discharge under high back pressure, stable and reliable operation, online calibration, and convenient operation and maintenance.
