Gas pressure regulator YQJX (F) series

diaphragmstainless steel 316Lbrass

Product description
The mini single-stage pressure regulators of the YQJX and YQJXF series are used to control gas pressure from steel cylinders under 8 L. They are suitable for analytical instruments, industrial gas supply, environmental instruments, the energy sector and other equipment that require precise inlet pressure control.

Product features

• Materials: Brass construction (YQJX) for non-corrosive gases.
• 316L stainless steel construction (YQJXF) for corrosive gases.
• Diaphragm: Metal diaphragm in the valve prevents secondary contamination of high‑purity gases by rubber diaphragms.
• High pressure resistance and excellent sealing performance.
• Simple, compact design: small, lightweight, durable, easy to operate and service-friendly for gas replacement.

Dimensions / Packaging
Packing size: 195 x 150 x 145 mm. Mounting holes located on the underside.
