Cylinder Valves

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

Cylinder valves for clean gases

  • Cylinder valves for clean gases
  • Cylinder valves for clean gases
OUTLINE
The diaphragm valves are highly recommended for ultra-high purify gas use. Manufactured through chemical polishing within the valve body. The assembly process took place in a clean booth.
