Bellows Seal Globe Valve is a new kind of globe valves with dual-seal. So its sealing is very good. The sealing surface is bead welding with hard alloy and the stem surface is in”nitrogen treatment”. Hence it is the valve of attrition-resistant, good anti-corrosion performance and long service life.
Series - 150 To 2500
Design Features
- Grease nipple. It can direct lubricate the stem, nut and sleeve
- Ergonomic hand wheel. It provide longer service life and easier operation
- Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life
- Double seal design ( bellows + packing ). Bellow and packing can protect against leakage and provide a excellent seal
- Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage
