Quick Detail

Single Plate Spring Check Valve, This product adopts clip-on connection, compact structure, and the valve flap moves along the center for lifting movement. Due to the short closing stroke of the valve flap and spring loading, the closing speed is fast, which can significantly reduce the water hammer. phenomenon. Single Plate Spring Check Valve has the characteristics of small size, light weight, sensitive action, reliable sealing and convenient installation. It is especially suitable for occasions where the installation space is limited. single-plate lift check valve can be applied to water. , vapor, oil, nitric acid, acetic acid, strong oxidizing medium and other media.Characteristics

1. The utility model has the advantages of short structure, small volume and light weight;

2. The valve flap is closed quickly and the water hammer pressure is small;

3. Smooth flow path, low fluid resistance; sensitive action, good sealing performance
