The plot operated safety pressure relieve valve, newly-structured, is mainly appied in such fields as petroleum & natural gas, chemistry, electic, metall-urgy & city gas. it is the best overpressure protecting equipment for pressure equipment, containers or pipelines. It is mainly characterized by shifting direct action of spring to indirect acton or guide valve, thus improving action sensitivty. What's more, the main valve, applying sleeve piston, is characterized by high precision of acton, good repetition, high reseating pressure, zero leakage, discharge with high back pressure, stable and reliable operation, online calibration,and convenience in operating and maintaining.
