Switch valve bellows seal
Thread Content
Are there any on-off valves available with diaphragm sealing, and are they effective?
Yes. Those that are highly toxic must be provided in accordance with regulations.
Yes, there are. For example, among globe valves, there are diaphragm-type globe valves
The so-called bellows structure must be used on linear-motion valves; angular-motion valves cannot be equipped with bellows. Therefore, gate valves, stop valves, or GLOBE stop valves can be used
