Victor 0780-1221 Extra Heavy-duty Line Regulator

Product Description

The VICTOR 0780-1221 is an extra heavy-duty line regulator from the L 700 Series, designed for gas distribution pipeline systems handling air, oxygen, inert gas, CO2, and N2O. It delivers outlet pressure in the 10 to 200 psig range and accepts a maximum inlet pressure of 350 psig. The forged brass body measures approximately 8.9 inches long, 8.5 inches wide, and 8.1 inches tall, and the unit weighs 6 pounds. A stem-type seat mechanism and externally dome-loaded design contribute to long service life under continuous pipeline demand. Licensed professionals in industrial gas, HVAC, and laboratory distribution install this regulator.

The 0780-1221 is suited for permanent pipeline and gas distribution systems that supply air, oxygen, inert gases, CO2, or N2O. The regulator accepts 1/2 inch NPT female inlet and outlet ports and is also compatible with gas distribution systems equipped with 3/4 inch NPT female inlet ports. It is not rated for direct cylinder service. Typical installations include manifold supply headers, laboratory gas panels, and industrial process lines where stable downstream pressure is required over extended run times.

Key Features

• Forged brass body and housing cap for durability in continuous pipeline service
• Stem-type seat mechanism for long-term seat integrity
• Delrin cap bushing provides smooth, consistent pressure adjustment
• Externally dome-loaded design supports remote pressure adjustment capability
• 3-1/4 inch neoprene diaphragm rated to 350 psig maximum inlet pressure
• Handles air, oxygen, inert gas, CO2, and N2O in a single regulator platform

Compatibility

Designed for use with gas distribution pipeline systems equipped with 1/2 inch NPT female or 3/4 inch NPT female inlet ports. Not suitable for direct cylinder use.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed gas systems and applicable codes such as NFPA 55 and CGA standards. Shut off and bleed the upstream supply line before removing or installing the regulator. Verify inlet and outlet port thread compatibility and use appropriate thread sealant rated for the gas service. Do not exceed the 350 psig maximum inlet pressure rating.
