GMK DIN Standard Bellows Seal Globe Valve
The components of the valve stem that make up a Bellows Seal Globe Valve are hermetically sealed using bellows, which results in a design that is more compact. Inside the bellows valve is where you'll find the bellows, and thanks to the stainless steel bellows that are welded to the stem at their lower end, the stem is shielded from the corrosion that can be caused by the fluid in the system. The other end is then put between the cover and the body of the valve to create a seal that will last. This design features a double seal to ensure that there are no leaks; even if the bellows fail to function properly, the stem package will cover any residual gaps. The bellows are welded to the stem of the valve in order to prevent the stem from vibrating as a result of the movement of the valve insert.
