Bellow Seal GGG25 Cast Iron Globe Valve DN15-DN200

Ductile Iron/Cast Iron Beloow Seal Globe Valve DN15-DN200

1. PRODUCT PROFILE

Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk. In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. Typically, automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly.

2. FEATURES

· 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.
· 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.
· Grease nipple. It can direct lubricate the stem, nut and sleeve.
· Ergonomic hand wheel. It provide longer service life and easier operation.

· High tightness
