The hot oil system, steam system, hot and cold water system, etc.
Advantage
1.Bellow seal element. The key part of bellow sealed globe valves is mental below. It is the connection between cover and stems with automatic roll welding. The mental bellow can keep the stem part no leakage.
2.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide an excellent seal.
3.Grease nipple. It can direct lubricate the stem, nut, and sleeve.
4.Ergonomic handwheel. It provides longer service life and easier operation.
