API Check Valve

Jinqiu Valve, a professional check valves manufacturer in China, our API check valves are designed and manufactured entirely according to American standards. These valves feature an aesthetically pleasing structure and advanced technology. API check valves automatically open and close the valve disc based on the flow of the medium itself to prevent backflow. They are also known as one-way valves, check valves, or backflow valves. Their main functions are to prevent backflow of the medium, prevent pump and drive motor reversal, and prevent leakage of the medium inside the container.

1. Low Flow Resistance: When the API check valve is fully open, the flow path is almost unobstructed, resulting in a low pressure drop.
2. Quick Closure and Backflow Prevention: The lever action of the valve disc allows for a rapid response and closure even at the onset of backflow.
3. Wide Applicability: Suitable for a wide range of pipe diameters, from DN50 to DN1200 and above.
