Our factory imported high-tech valve manufacturing technology from Europe to produce the elastic seat seal gate valve, which uses the whole gate rubber to produce deformation compensation effect, and achieves good sealing effect, water leakage and rust phenomenon. It can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, ship, metallurgy, energy system and other fluid pipelines as well as the use of interceptor.
2, Features:
1. Integral rubber coating: the valve adopts integral rubber coating, its good covering performance and geometric dimension ensure reliable sealing and long service life.
2. Light weight: the valve body is made of ductile iron, light in weight and easy to install.
3. Flat bottom valve seat: the bottom adopts the same flat bottom seat design as the water pipe, which does not produce debris deposition, and the sealing is more reliable.
4. Corrosion resistance: the inner cavity is coated with epoxy resin to prevent corrosion and rust. It can be used not only for drinking, but also for sewage system.
5. Three "O" seal: the valve rod is sealed with three O-rings, with small friction resistance, light switch and no water leakage.

Main performance specifications:
For a long time, the general gate valve used in the market has the phenomenon of water leakage and easy rusting. The soft seal gate valve produced by our factory with foreign advanced technology overcomes the general gate valve seal elastic fatigue and easy rusting. The soft seal gate valve uses the elastic gate to produce a small amount of deformation compensation to achieve good sealing effect. The valve has the advantages of light switch, reliable sealing, good elastic memory and long service life.
Application:
It can be widely used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy system and other fluid pipelines as a regulating and intercepting device.
