Check valves are essential components in high-pressure pipelines, ensuring fluid flows only in the desired direction while effectively preventing any backflow to the pump, thereby safeguarding the entire pipeline system.
The API 6A Check Valve is ingeniously designed with self-operative opening and closing functions, reliant solely on the flow dynamics of the medium. It's ideal for use with clean mediums and not recommended for those containing solid particles or with higher viscosity.
Design Features:
With its well-engineered structure, this valve guarantees reliable sealing and boasts an aesthetically pleasing appearance.
The valve disc is engineered for rapid closure and flexible operation, enhancing overall system efficiency.
Enjoy the benefits of low maintenance costs with our expertly crafted valves.
Designed to minimize operational upkeep, our valves require no short-term regular lubrication or maintenance.
Our check valves are available in three distinct types: top-entry, dart, and flapper. The top-entry and flapper variants feature fully encapsulated flappers, increasing abrasion resistance and are primarily used in fluid services. Dart check valves boast dual seals, crafted from stainless steel and seal rings, making them particularly suitable for gas services.
