Pilot Operated Safety Valv

Pilot operated safety valve, newly -structure, is mainly applied to such trades as petroleum & natural gas, Chemistry, electric, metallurgy & burning gas. It is the best super-pressure protecting equipment on press equipment, Container, or pipeline.

Series - 150 To 900

It is mainly characterized by shifting direct function of spring to indirect function of guide valve, What’s more, main valve, applying for sleeve piston & double sealed seat. It is characterized by high precision of action, good recycling function, fast turning back to seat, ability to high-pressure leaking, long working time & security, together with read-adjustment on line, automatic turning back to seat after leaking again and again, tight closure, operating and maintaining convenience.
