The extended rod gate valve is one of the commonly used block valves, which is mainly used to put through or cut off the medium in the pipeline; Especially suitable for medium and large diameter pipe. The stem of the soft seal gate valve drives the stem of the gate to lift together. The transmission thread on the stem is outside the valve body. Therefore, the opening and closing and position of the gate can be determined intuitively according to the direction and position of the valve stem, and the transmission thread is easy to lubricated and free from fluid corrosion, but it requires a large installation space.
Features:
Valve stem lengthening, convenient for high position operation;
Smooth channel, flow coefficient is small;
Reliable sealing, light and flexible operation
