Non rising stem elastic seat seal gate valve

Short Description:

Z45x Non rising stem gate valve elastic seat seal gate valve uses the deformation compensation function of the whole gate valve to produce a good sealing effect, overcomes the phenomenon of poor sealing, water leakage and rust of general gate valve, and saves installation control more effectively. It can be widely used as regulator and throttling device in water, sewage, construction, petroleum, chemical, food, medicine, light textile, electric power, ship, metallurgy, energy system and other fluid pipelines.
