Products Details

AX46F pilot operated safety valve

Its main advantage is that the direct action of spring is changed into the indirect action of pilot valve, which improves the sensitivity of action. Moreover, the main valve adopts sleeve piston type and double seal seat structure, which has high action precision, good repeatability, quick return, no leakage, high back pressure discharge, long working life, stable and reliable work. It can also be adjusted online, and can still return to seat automatically after repeated start-up and discharge, Closed tightly, easy to operate and maintain.
