Technical specification
Design standard: ASME B16.34
Face to face dimension: ASME B16.10
Flanged ends: ASME B16.5
Test & inspection: API 598

Application
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 bellow. It is the connection between cover and stem with automatic roll welding. The mental bellow can keep the stem part no leakage.
2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.
3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
4.Grease nipple. It can direct lubricate the stem, nut and sleeve.
5.Size above DN150 with triangle position device. It can protect internal parts from shaking, less noise and more tensile strength.
6.Different disc design for different work condition, regulating disc, globe-check disc, soft seal disc etc.
7.Ergonomic hand wheel. It provide longer service life and easier operation.
