These Japanese KHK certified valve are intended for seamless cylinder. Since inner structure is similar to that of cylinder valves, smooth handle movement is guaranteed even under high pressure environment. Both packed and diaphraigm valves are available in brass and SUS to meet various needs.
High-pressure gas cylinder valves - Diaphragm Valves
- OUTLINE
- Metal thin plate called diaphragm is fixed between the body and grand nut for sealing structure. High air tightness. Well-chosen for semi-conductor gases.
