**Overview: Ultra High Temperature Ball Valve**
The company's design team has developed an advanced high-temperature ball valve that utilizes a new sealing material for the seat. Compared to traditional PTFE-sealed ball valves, this model significantly extends service life by 3 to 5 times. The valve offers stable performance, reliable sealing, low friction, smooth operation, and excellent resistance to high temperatures, wear, oil, and corrosion. It is ideal for use in industries such as petroleum, chemical, rubber, paper, and pharmaceuticals, where it can replace other types of valves like gate valves, plunger valves, and quick drain valves.
**Suitable Media:** Water, steam, oil, acids (such as nitric acid and acetic acid).
**Maximum Operating Temperature:** ≤ 350°C
