Product Overview
The characteristics of the integrated flange ball valve are consistent with the structural length of the globe valve, plunger valve, and drain valve, expanding the range of ball valve use. The ball valve, which uses a new sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene, has increased its service life by 3-5 times. It has the advantages of stable performance, reliable sealing, low friction, lightweight switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. Widely used in industries such as petroleum, chemical, rubber, papermaking, pharmaceuticals, etc., it can replace globe valves, plunger valves, and quick drain valves.
Product Features
1. Low flow resistance;
2. Simple structure;
3. Small size and light weight;
4. Currently, the sealing surface material of ball valves is made of plastic, which has good sealing performance;
5. Convenient operation, quick opening and closing, and easy remote control;
6. Convenient maintenance, sealing rings are generally movable, making disassembly and replacement convenient;
7.When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and the passage of the medium will not cause erosion of the sealing surface of the ball valve.
