Product Description

Pilot Operated Safety Relief Valve
Pilot Operated Safety Valve, the best super-pressure protecting equipment on pressure equipment, container or pipeline. Soft/Metal to Metal seal.

Pilot operated safety valve, newly structured--is mainly applied to such trades as petroleum & natural gas, chemistry, electric, metallurg & burning gas. It is the best super-pressure protecting equipment on pressure equipment, container or pipeline. It is mainly characteized by shifting direct function of spring to indirect function of quide valve. What's more, main valve, applying for sleeve piston & double sealed seat, is characterized by high precision of action, good recycling function fast turning back to seat, ability to high pressure leaking, long working time and security, together with read-justment on line, automatic turning back to saet after leaking again and again, tight closure,operating and maintaining convenience.
