Check Valve

We offer a variety of check valves, including Swing Check Valves, Lifting Check Valves, Tilting Check Valves and Wafer Check Valves.

Check valves, also known as non-return or one-way valves, are mechanical devices designed to allow fluid (liquid or gas) to flow in only one direction. These valves prevent backflow by automatically closing when the flow direction reverses. An essential feature of check valves is the cracking pressure, which refers to the minimum upstream pressure required for the valve to open and allow flow.

Check valves can be tailored to specific applications based on their cracking pressure, ensuring they function efficiently in a range of systems and industries. They are commonly used in applications where preventing reverse flow is critical, such as in water supply, oil and gas pipelines, and HVAC systems.
