GGG25 / GGG50 Bellow Seal Globe Valve PN16 Pressure

GGG25/GGG50 Bellow Seal Globe Valve

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.

The bellow seal globe valve is operated as an obstruction between fluids and the air. At the same time, the valve can prevent fluids leaking to the air and guarantee zero leakage of pipelines. The bottom of bellows is welded to the valve stem of the bellow seal globe valve to avoid process fluids eroding the valve stem.The globe valve of this type s recommended for service with No corrosive or no toxic fluids, steam, hydrocarbons, thermic fluid. The carbon steel globe valve’s stem and seat is made from stainless steel. It follows the flow direction indicated by the arrow.

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
