Product description

       The stainless steel open-rod elastic seat-sealed gate valve is a new type of product. It is adapted to the water system by introducing advanced foreign technology and adapted to the water system, which overcomes the defects of poor sealing, elastic fatigue, and easy rusting of general gate valves. The elastic seat seal gate valve is a replacement product of the traditional gate valve. It uses the compensation effect of the elastic gate plate to produce a small amount of deformation to achieve a good sealing effect. The valve has the obvious advantages of light switch, reliable sealing, good elastic memory and long service life, and can be widely used. Used in fluid pipelines such as tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems, etc. as regulating and intercepting devices.

Features of the product

1. Overall encapsulation: The gate adopts an overall encapsulation. Its good covering performance and precise geometric dimensions ensure reliable sealing and longevity.

2. Light weight: The valve body is made of ductile iron, which is light in weight and easy to install.

3. Flat-bottomed valve seat: The bottom adopts the same flat-bottomed valve seat design as the water pipe, which does not produce debris and makes the seal more reliable.

4. Corrosion resistance: The inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust. Not only can it be used for raw drinking, but also can be used in sewage systems.

5. Three "O" seals: The valve stem adopts three O-ring seals, with low friction resistance, light switch and no water leakage.
