Soft Seal Gate Valve

Soft sealed gate valve refers to a gate valve whose opening and closing parts, such as valve disc and valve plate, are completely covered with rubber on the outer surface. It is mainly used in the pipeline equipment of water supply and drainage fields such as buildings, fire protection, and water plants in urban construction. The soft sealed gate valves produced by Shanghai Meiyan Yi Pump Valve are divided into two types: rising stem soft sealed gate valves (when the valve is opened and closed, the valve stem can be seen to rise or fall) and hidden stem soft sealed gate valves (when the valve stem rotates, the valve stem cannot be seen to rise or fall, and the gate inside the valve will rise or fall with the valve stem screw). Usually, there are trapezoidal threads on the lifting rod, and through the nut in the middle of the gate and the guide groove on the valve body, the rotational motion is converted into linear motion, that is, the operating torque is converted into operating thrust.
