Victor 0781-1455 High Pressure Piston Regulator Npt

Product Description

The VICTOR 0781-1455 is a heavy-duty, high-pressure piston regulator built for demanding pressure vessel and dead-end testing applications. The machined brass body and housing cap provide durability under high-cycle use. A cartridge-type seat assembly with a PCTFE seat ensures consistent sealing performance at elevated pressures. A Delrin cap bushing allows smooth, precise delivery pressure adjustments. Qualified technicians and industrial service professionals working with compressed gas systems will find this regulator suited to high-demand bench and field testing scenarios where reliable pressure control is critical.

This regulator is designed for high-pressure service environments including pressure vessel testing and dead-end system testing. The 1/4 inch NPT inlet connection is standard for many compressed gas supply lines. The sintered bronze inlet filter protects internal components from particulate contamination. Models in the F and G range include external adjustable relief valves. Hydrogen-compatible models feature ventable relief valves; note that J Series models do not include this feature.

Compatibility

Designed for use with compressed gas systems requiring high-pressure regulation up to 4500 PSIG; compatible with pressure vessel and dead-end testing setups using a 1/4 inch NPT inlet connection.

Installation Notes

Installation should be performed by a qualified technician familiar with high-pressure compressed gas systems. Depressurize and isolate the gas supply completely before connecting or removing the regulator. Use appropriate thread sealant rated for high-pressure gas service on all NPT connections. Follow applicable codes and the regulator manufacturer guidelines for torque and pressure testing after installation.
