Use
The pilot operated safety pressure relieve valve, newly–structured, is mainly applied in such fields as petroleum & natural gas, chemistry, electric, metallurgy & 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 action of guide valve, thus improving action sensitivity. What’s more, the main valve, applying sleeve piston, is characterized by high precision of action, good repetition, high reseating pressure, zero leakage, discharge with high back pressure, stable and reliable operation, online calibration, and convenience in operating and maintaining.
