Check valves are widely used in high pressure pipeline to control fluids flowing in one way and stop fluids from flowing back to the pump, protecting pipeline safety. 
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 ;
We check valves are available in three types including top-entry, dart and flapper. T he top entry and flapper types adopt completely wrapped flappers which extend the abrasion life, and they are mainly used in fluid services. Dart check valves feature dual seals composed of stainless steel and seal ring and they are mainly used in gas services.
