A brass diaphragm valve that is highly versatile
because of its polished diaphragms and no-grease specification
G-55L Series
Brass Diaphragm Valve
A brass diaphragm valve for high-purity gas with a track record. The same structure as the SUS-55L ensures high airtightness. With polished diaphragms and its non-grease specification, it can be used for high-purity gases, specialty gases, and other fluids that do not tolerate water or oil.
Features
- The valve body is C3771 brass.
- The same structure as the stainless steel diaphragm valve SUS-55L ensures high durability.
- The Cv value is no less than 0.3, the reference value for compressed gas valves.
- For common high-pressure gases, compatible with both compressed and liquefied gases.
- Compatible with various industrial and high-purity gases.
- In the lineup are those for small cylinders (V1) (excluding CO₂) and GX-55L with open/close markings on the handle.
