Soft sealed dark stem gate valve

Product Overview

Soft sealing of dark stem gate valve can make use of the deformation compensation effect generated by the integral seal of the gate to achieve good sealing effect, overcome the phenomenon of poor seal, leakage and rust of general gate valve, and save installation space more effectively.
It can be widely used as regulator and closure device in the fluid pipeline of tap water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ship, metallurgy, energy system, etc.

Structural characteristics

1. Monolithic packing: The dark stem soft sealing gate valve gate adopts monolithic packing, which has good covering performance and accurate geometric size, ensuring the sealing reliability and life.
2. Light weight: the valve body is made of ball iron, light weight and easy to install.
3. Flat bottom valve seat: the bottom adopts the same flat bottom valve seat design as the water pipe, no debris accumulation, the sealing is more reliable.
4. Corrosion resistance: The inner cavity of the gate valve is coated with non-toxic epoxy resin to prevent corrosion and rust. It can not only be used for drinking, but also for sewage system.
5. Three "0" seal: the stem adopts three 0-ring seals, small friction resistance, light switch, no water leakage.
