Product Overview
The flange rising stem gate valve adopts an external valve stem structure, and the valve stem rotates and moves axially. The gate moves up and down with the valve stem to open and close, and the valve opening can be directly observed. It is widely used in pipeline projects such as water supply and drainage, fire protection, air conditioning, water treatment, municipal administration, shipbuilding, electric power, construction, and food to transport fluid pipelines as a control fluid.
Features
1. The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium.
2. Opening and closing require less effort.
3. The flow direction of the medium is not restricted, the flow is not disturbed, and the pressure is not reduced.
4. Simple shape, short structural length, good manufacturing process, and wide application range.
