Victor 0781-5223 Two Stage Inert Gas Regulator 10-200 Psig

Product Description

The VICTOR 0781-5223 is a two-stage, high-capacity inert gas regulator engineered for applications that demand precise and stable outlet pressure across varying cylinder pressures. Part of the Victor ETS4 EDGE Series, it delivers a 10-200 psig outlet pressure range with a maximum inlet pressure of 3000 psig. The forged brass body, zinc-aluminum housing caps, and high-impact ABS gauge guards provide durable protection in industrial environments. A 0.488 Cv flow coefficient ensures uniform flow performance with high sensitivity. Licensed tradespeople in industrial gas, welding, and fabrication shops are the primary installers of this regulator.

This regulator is suited for industrial and general fabrication, light fabrication, repair and maintenance, and structural steel fabrication. The 580 CGA inlet connection pairs with a 5/8 inches-18 RH(F) outlet connection. The compact layout features built-in gauges recessed into the body, color-coded knobs for quick gas identification, and a side-mounted SLAM impact-absorbing safety knob that supports natural hand and body positioning during pressure adjustment. The recessed single impact point is configured to protect components critical to system integrity.

Key Features

• Forged brass body with zinc-aluminum housing caps for strength and corrosion resistance
• 2.7 inches fabric-reinforced neoprene diaphragm for reliable pressure response
• 1.5 inches UL listed/recognized gauges: 4000 psig inlet range, 400 psig outlet range
• External self-reseating relief valve and stem-type seat mechanism
• Nickel-plated bronze sintered inlet filter for contamination protection
• Color-coded SLAM impact-absorbing safety knob protects regulator internals
• Meets or exceeds CGA E-4, UL 252, and ASTM G-175 promoted ignition test standards

Compatibility

Designed for use with inert gas cylinder systems using a 580 CGA inlet connection in industrial fabrication, repair, and maintenance applications.

Installation Notes

Installation should be performed by a qualified gas systems technician or welder familiar with compressed gas regulator service. Shut off the cylinder valve and verify the system is fully depressurized before connecting or disconnecting the regulator. Inspect the inlet filter and connection threads before attaching to the cylinder. Follow all applicable CGA guidelines and local compressed gas safety codes during installation and servicing.
