Test Pressure

Brief introduction:

The check valve is designed and manufactured according well to API 6D and ANSI B 16.34. It can

work in

high temperature and pressure circumstance. It also have the features of good appearance, nice

function and

superior. Widely used for petroleum, chemistry, water treatment industries.

Features:

- Resist friction

Valve disc is given enough intensity and rigidity. Disc sealing surface may be built up welded with

satellite alloy inlaid or other material responding to the users’ request.

- Agility of switch

Solid ping is precisely installed and provided with high intensity to ensure operational performance

and service life of valve.

- Sealing credibility

The check valve adopt swing configuration. All the sealing part inside the valve, so all exterior leak

may except the middle flange, and also the middle flange gasket may be different

according to pressure class.

- Distortion compensating
