Bellow Seal Gate Valve
Home / Bellow Seal Gate Valve
Forged Steel Bellow Gate Valve
Technical specification
Design standard: DIN 3352
Face to face dimension: DIN 3202
Flanged ends: DIN 2543-2545
Test & inspection: DIN 3230
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.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.
