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 valve plate is fully covered with rubber, which has good covering performance and precise size, ensuring the reliability of the seal;
2. The bottom of the valve adopts the same flat bottom type as the water pipe, which does not cause debris accumulation;
3. The entire valve is painted with non-toxic epoxy resin to prevent corrosion and rust. It can be used not only for drinking water systems but also for sewage systems;
4. The gland nut is used for self-tightening sealing; greatly improving the sealing performance;
5. It is extremely convenient to replace the sealing-wearing parts.
