Working Principle of Wafer Check Valve: The disc of the wafer lift check valve moves up and down along the central positioning. Due to the short closing stroke of the disc and spring loading, the closing speed is fast, which can significantly reduce water hammer. The product features compact size, light weight, sensitive action, reliable sealing, and easy installation. It is especially suitable for applications where installation space is limited. Features: 1. Short structure, compact size, and light weight. 2. Fast disc closing and low water hammer pressure. 3. Smooth flow path with low fluid resistance; sensitive action and excellent sealing performance. 4. Easy installation, can be installed in both horizontal and vertical pipelines. 5. The disc is designed with dual plates and two torsion springs, enabling rapid self-closing. 6. The rapid closing function prevents medium backflow and effectively eliminates water hammer.
