Victor 0781-1401 Single Stage CO2 Regulator 50-750 Psig

Product Description

The VICTOR 0781-1401 is a heavy-duty, single-stage, high-pressure carbon dioxide piston regulator designed for demanding industrial gas applications. It delivers outlet pressure in the range of 50 to 750 psig against a maximum inlet pressure of 3000 psig. The body is machined brass with a brass housing cap. Actuation is piston-type with a Delrin cap bushing for smooth, consistent adjustments. A cartridge-type seat assembly with a PCTFE seat provides reliable shutoff. Inlet connection is CGA 320 with a bronze sintered filter. The outlet is a 5/8 inches-18 UNF connection fitted with a 1/4 inches stainless tube fitting. Gauges are 2.5 inches brass. An external adjustable relief valve is included.

This regulator is suited for pressure vessel testing, dead-end testing, and other high-pressure CO2 applications where precise, stable delivery pressure is required. The heavy-duty construction targets industrial and laboratory environments where continuous or high-cycle service is expected. Licensed gas technicians and industrial piping professionals are the typical installers for this class of equipment.

Key Features

• Machined brass body and housing cap for durability in high-pressure service
• Cartridge-type seat assembly with PCTFE seat for reliable sealing
• Piston-type actuation with Delrin cap bushing for smooth outlet pressure adjustment
• CGA 320 inlet with bronze sintered filter to protect internals from contamination
• External adjustable relief valve provides overpressure protection
• 2.5 inches brass gauges for inlet and outlet pressure indication

Compatibility

Designed for use with carbon dioxide (CO2) gas supply cylinders using a CGA 320 inlet connection. Suited for pressure vessel testing and dead-end testing applications requiring 50 to 750 psig delivery pressure at up to 3000 psig inlet.

Installation Notes

Installation should be performed by a qualified gas technician familiar with high-pressure compressed gas systems and applicable codes. Always close the cylinder valve and bleed system pressure before connecting or disconnecting the regulator. Inspect the CGA 320 inlet connection and sintered filter for debris before use. Do not exceed the rated maximum inlet pressure of 3000 psig.
