Purpose:
Our factory imports the elastic seat sealing valve produced by the European high-tech valve manufacturing technology, and uses the whole gate glue to produce deformation compensation effect to achieve good sealing effect, which overcomes the phenomenon of poor sealing, leakage and rust of general gate valves. It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, power, ship, metallurgy, energy system and other fluid pipelines as well as interception devices.
2. Characteristics:
1. Integral gluing: The valve adopts integral gluing. Its good covering performance and geometric size ensure reliable sealing and long service life.
2. Light weight: The valve body is made of ductile iron, light weight and easy to install.
3. Flat-bottomed seat: The bottom adopts the same flat-bottomed seat design as the water pipe, which does not produce sundries and is reliable in sealing.
4. Corrosion resistance: The inner cavity is coated with epoxy resin to prevent corrosion and rust. It can be used not only for raw drinking, but also for sewage system.
5. Three "O" seals: Stem is sealed with three O-rings, with small friction resistance, light switch and no leakage.
