Victor 0781-1424 Single Stage High Pressure Regulator

Product Description

The VICTOR 0781-1424 is a heavy-duty, single-stage, high-capacity piston regulator designed for methane and hydrogen service. Built around a machined brass body with housing cap, it accepts inlet pressures up to 3000 psig and delivers regulated output in the range of 100 to 1500 psig. The brass piston features a Delrin cap bushing for smooth, consistent pressure adjustment. A cartridge-type seat assembly with a PCTFE seat provides reliable shutoff, and an external adjustable relief valve adds a layer of overpressure protection. Licensed technicians and lab professionals working with high-pressure specialty gas systems will find this regulator suited to demanding service conditions.

The 0781-1424 is built for applications requiring precise high-pressure gas delivery, particularly pressure vessel testing and dead-end testing scenarios. The CGA 350 inlet connection with a bronze sintered filter protects internal components from particulate contamination. The outlet uses a 1/4 inch Swagelok fitting with a 1/4 inch stainless tube fitting for secure, leak-resistant connections. This regulator is appropriate for industrial and laboratory environments where methane or hydrogen is supplied from high-pressure cylinders and controlled delivery is critical.

Key Features

• Machined brass body and housing cap for durability in high-pressure gas service
• Cartridge-type seat assembly with PCTFE seat for reliable sealing
• Brass piston actuation with Delrin cap bushing for smooth pressure adjustment
• External adjustable relief valve for overpressure protection
• CGA 350 inlet connection with bronze sintered filter to protect internals
• 1/4 inch Swagelok outlet with stainless tube fitting for secure connections
• 2.5 inch brass gauges for inlet and outlet pressure monitoring

Compatibility

Designed for use with methane and hydrogen gas systems requiring a CGA 350 inlet connection. Suitable for pressure vessel testing and dead-end testing applications where inlet pressures up to 3000 psig and delivery pressures of 100 to 1500 psig are required.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure specialty gas systems and applicable codes. Ensure the gas supply is fully shut off and the system is depressurized before connecting or disconnecting the regulator. Verify that all fittings, including the Swagelok outlet connection, are properly seated and leak-tested after installation. Follow all applicable safety standards and manufacturer guidelines for hydrogen and methane service.
