Victor 0781-1422 Single Stage High Pressure Air Regulator

Product Description

The VICTOR 0781-1422 is a heavy-duty, single-stage, high-pressure piston regulator designed for air and compatible gases. Built around a machined brass body with housing cap, it accepts inlet pressures up to 3000 psig and delivers regulated output from 100 to 1500 psig. The piston-type actuator uses a Delrin cap bushing for smooth, consistent adjustments across the delivery range. A cartridge-type seat assembly with a PCTFE seat provides reliable shutoff and repeatable pressure control. This regulator is installed by industrial gas technicians and testing engineers in high-pressure service applications.

The 0781-1422 is configured for pressure vessel and dead-end testing applications where stable, adjustable high-pressure delivery is required. It features a 346 CGA inlet connection with a bronze sintered filter to protect downstream components from particulate contamination. The outlet is a 1/4 inch Swagelok connection with a 1/4 inch stainless tube fitting. An external adjustable relief valve provides overpressure protection. The unit measures 6.1 inches by 7.5 inches by 8.6 inches and weighs 4.5 pounds.

Key Features

• Machined brass body and housing cap for durability in high-pressure service
• Piston-type actuation with Delrin cap bushing for smooth delivery pressure adjustment
• Cartridge-type seat assembly with PCTFE seat for reliable shutoff
• 346 CGA inlet connection with bronze sintered filter
• 1/4 inch Swagelok outlet with stainless tube fitting
• External adjustable relief valve for overpressure protection

Compatibility

Designed for use with air gas service requiring a 346 CGA inlet connection; suited for pressure vessel testing and dead-end testing setups where inlet pressures up to 3000 psig and delivery pressures from 100 to 1500 psig are required.

Installation Notes

Installation should be performed by a qualified industrial gas technician or engineer familiar with high-pressure gas system codes. Before connecting or disconnecting the regulator, verify that the upstream supply is fully shut off and the downstream system is depressurized. Inspect the CGA inlet connection and sintered filter for contamination or damage prior to installation. Follow all applicable compressed gas and pressure vessel codes for your jurisdiction when integrating this regulator into a test system.
