Bellows Seal Globe Valve is a compact structure that is a kind of control valve which uses bellows for sealing the valve stem components. The bellows valve has a bellow inside, and the lower end of the stainless-steel bellows is welded to the stem to prevent the system fluid from eroding the stem.
5.Ergonomic hand wheel. It provide longer service life and easier operation.
Long cycle life bellows (10,000 cycles): Designed and qualification tested for high pressure/temperature applications.
Bellows monitoring port (optional): A plug can be connected to the space above the bellows to monitor performance.
Two secondary stem seals: a) Backseat in open position; b) Graphite packing.
Superior seating faces: Seats hardfaced with CoCr alloy, disc is solid CoCr alloy.
