Product overview
The electric seat-sealed gate valve can be equipped with various electric actuators according to users' requirements to realize remote control and automatic control. It has the advantages of sensitivity, reliability and convenient installation. It can be widely used as a regulating and intercepting device on the fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ship, metallurgy, energy system and so on.
Product features
1, Flat-bottom valve seat, no dirt accumulation, make the seal more reliable.
2. The valve disc is coated with nitrile rubber as a whole, and the valve internals are made of corrosion-resistant stainless steel and copper alloy materials, which can be used for the working ring of the sewage system with poor adaptability.
3. Small volume, light weight and convenient installation and maintenance.
4. The valve stem is sealed with three O-rings, which greatly reduces the friction resistance during switching, and the switch is light and watertight.
