Advantage
1.Bellow seal element. The key part of bellow sealed globe valves is mental bellow. It is the connection between cover and stem 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 a excellent seal.
3.Grease nipple. It can direct lubricate the stem, nut and sleeve.
4.Ergonomic hand wheel. It provide longer service life and easier operation.
