CXV Dual Plate Check Valve design,manufacturing are strictly following API 594 Standard.Before delievery,our inspector test the valves strictly following API594 standard,to make sure 100% good quality.

CXV Features and benefits:

Retainerless emission-free design. With no holes through the body wall, leakage to the outside is impossible.
Body surface with uninterrupted gasket surface.
Intrinsically fire safe.
The reduced weight of the disc minimizes slamming and water hammer.
The disc side hinges, eliminate the effect of gravity resulting in lower energy costs when installed in a horizontal pipeline.
Design maximizes the flow path area through the valve with a lower pressure drop. The internal retention method does not encroach on the gasket sealing surface.
Springs provide a fast-acting response to flow reversal, minimizing stress and maximizing service life.
Shock bumpers extended cycle life of internal components with minimal wear in severe service.
Extended seat life due to the clearance between the disc hinge and hinge pin which eliminates any dragging effect from the discs.

CXV dual plate check valves easily meet and exceed test requirements of API 598 for metal-seated check valves.
