Product Description

REGO AR4106A300 3/4″ MNPT × 1″ FNPT 300 PSIG Angle Pressure Relief Valve

The REGO AR4106A300 is an ASME-approved 90° angle pressure relief valve designed to provide over-pressure protection for compatible cryogenic vessels and piping systems.

This configuration features a 3/4″ male NPT inlet, 1″ female NPT outlet, and a factory-set pressure of 300 PSIG. The AR Series uses a 90° flow path to direct relieved gas away from the spring area and incorporates a bubble-tight seat designed to shut off when the valve reseats.

The valve is cleaned for oxygen service per CGA G-4.1 and is factory tested. REGO documentation lists the AR4100 Series for cryogenic applications including oxygen, nitrogen, argon, carbon dioxide, LNG and other compatible gases/liquids.
