The grooved soft-sealed gate valve adopts a new type of steel pipe connection method, also known as clamp connection, which has many advantages. The design code for Automatic Sprinkler fire extinguishing Systems stipulates that the connection of system pipelines should adopt grooved connectors or threaded and flanged connections. Pipes with a diameter of 65mm or more in the system should be connected in sections using flanges or grooved connectors.
The grooved soft-sealed gate valve is produced by introducing high-tech rubber and valve manufacturing technology from Europe, overcoming the defects of rubber aging and rusting. This valve achieves a good sealing effect by compensating for the slight elastic deformation of the elastic gate plate. It has significant advantages such as light operation, reliable sealing, excellent elastic memory and long service life. The products are widely used in pipelines of industries such as tap water, sewage, seawater, water treatment, environmental protection, construction, fire protection, petroleum, chemical engineering, power, food, medicine, light textile, shipping, and energy as regulating and shut-off devices.
