High Quality Cast Iron/Ductile Iron Bellow Seal Globe Valve

GGG25/GGG50 Bellow Seal Globe Valve

1. PRODUCT PROFILE

Bellow Seal Globe Valve is a mechanism used to control or stop the flow of liquid or gas through a pipe. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with a disk or plug.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.

2. FEATURES
