Z81X-16 groove rising stem elastic seat sealing gate valve

Z81X-16 groove rising stem elastic seat sealing gate valve is easy to maintain, install, and has low cost. It is widely used in industries such as water supply and drainage, fire protection, buildings, power, metallurgy, etc., as a shut-off device

The valve stem and valve cover of Z81X-16 groove rising stem elastic seat sealed gate valve are designed with three "O" ring seals, which can reduce frictional resistance during opening and closing, significantly reduce water leakage, and allow for continuous flow of medium in the pipeline by replacing the seals. In addition, due to the internal coating of the valve body with epoxy resin, the inner and outer surfaces of the valve plate are covered with rubber to prevent the occurrence of molten iron or corrosion, making it suitable for drinking

When the Z81X-16 groove rising stem elastic seat sealing gate valve is closed, the sealing surface can be sealed solely by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side by the medium pressure to seal the surface, which is self sealing. Most groove gate valves use forced sealing, which means that when the valve is closed, external force must be used to forcefully press the gate plate against the valve seat to ensure the sealing performance of the sealing surface

The gate of Z81X-16 groove rising stem elastic seat sealed gate valve moves in a straight line with the valve stem, which is called a rising stem gate valve or a rising stem gate valve. Usually, there are trapezoidal threads on the lifting rod. Through the nut of the valve and the guide groove on the valve body, the rotation is converted into linear motion, that is, the operating torque is converted into operating thrust
