Overview: Gate valve is one of the commonly used block valves, mainly used to connect or cut off the medium in the pipeline; Especially suitable for medium and large diameter pipelines. The stem of the rising stem gate valve drives the gate plate to rise and fall together. The transmission thread on the stem is located outside the valve body, so the opening and closing position of the gate plate can be intuitively determined based on the direction and position of the stem movement. Moreover, the transmission thread is easy to lubricate and not subject to fluid corrosion, but it requires a large installation space. Features: The valve stem is extended, making it easy to operate at high positions; Smooth channel with low flow coefficient; Reliable sealing, easy and flexible operation;
