The upper sealing structure between the valve stem and the valve cover of the national standard groove open stem soft seal gate valve adopts a sealing design of EPDM rubber sleeve. Compared with the packing sealing structure of traditional gate valves, the channel seal is tight, the friction resistance is greatly reduced, it is not easy to leak water, and the service life is long.
In addition to its compact structure, good valve rigidity, smooth passage, low flow resistance, high-quality EPDM encapsulation on the sealing surface, long service life, reliable sealing, and easy and flexible operation, the rising stem elastic seat sealing gate valve can also have a more intuitive valve opening and quick and reliable opening and closing, making it commonly used in fire and industrial systems.
