Through-flow check valves, also known as one-way valves or non-return valves, are a type of valve where the opening and closing mechanism operates automatically based on the flow and force of the medium to prevent reverse flow. Check valves belong to the category of automatic valves and are primarily used in pipelines that require unidirectional medium flow, allowing the medium to move in only one direction to prevent accidents.Main features of through-flow check valves:  Through-flow check valves, also known as one-way valves or non-return valves, are a type of valve where the opening and closing mechanism operates automatically based on the flow and force of the medium to prevent reverse flow.

1. Streamlined flow path ensures that the medium flows directly without detours, resulting in low flow resistance and energy savings.  

2. A special sealing structure is employed, ensuring tight closure and excellent sealing performance regardless of the downstream pressure. This overcomes the drawback of poor sealing performance in conventional check valves under low backpressure conditions.  Check Valve

3. A floating disc design automatically compensates for errors caused by wear during installation and use, ensuring tight contact of the sealing surfaces and improving sealing performance.  

4. Short opening and closing stroke with automatic reset and no impact. The valve fully opens even at low flow velocities and closes quickly.  Check Valve Suppliers

5. The valve can be installed in any position—horizontally, vertically, or at any angle—without restrictions.
