闸阀
Bellow seal valves are normally installed in working conditions that have strict emission requirements. Possible leakage arising from stem movement is eliminated by mounting a metal bellow between the bonnet and the stem. The bellow can follow the lineair movement of the stem easily, creating a stable and state of the art zero emission seal.
