Product Description

Check Valve

DEENPU API 6A Check Valve' opening and closing parts can be opened or closed by themselves depending on the flow of the medium, which is suitable for clean medium and not suitable for medium containing solid particles and larger viscosity .

Design Features :

Rational structure,reliable sealing ,pretty apperance;

The valve disc is closing rapid and actions flexible;

Low maintenance cost; 

There's no need for short term regular lubrication and maintenance ;

Check Valves are important part of wellhead equipment and widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety.

Flapper Check Valves - Clapper check valves are designed for well service applications such as fracturing, cementing and acidizing. The flapper check valve is placed in the treating line to allow flow to the well but isolates and back flow to go upstream in the valve. This provides a safety device at various locations in the flow line and assure that pressure and fluid can not backup into the manifold or into pumps.
