Bellows valve

Bellows valves are generally used in conditions where the leakage level has strict requirements, and the leakage causes harm to the operator or damage to the environment. The upper and lower ports of the bellows are fixed to the valve cover and the valve stem respectively. When the valve stem moves up and down, the bellows are driven to expand and expand, and the leakage caused by the sliding seal of the valve stem is eliminated.
