Product Description

REGO AR4112A250 1-1/2″ MNPT × 2″ FNPT 250 PSIG Cryogenic Angle Relief Valve

The REGO AR4112A250 is a 90° angle pressure relief valve designed to provide over-pressure protection for compatible cryogenic vessels, bulk storage tanks and piping systems.

This configuration features a 1-1/2″ male NPT inlet, 2″ female NPT outlet and 250 PSIG factory set pressure. The 90° design directs relieved gas away from the spring area and allows convenient integration into discharge piping. REGO specifies a bubble-tight seat designed to provide shutoff when the valve reseats.

The AR Series is cleaned for oxygen service per CGA G-4.1 and is 100% factory tested. REGO lists the series for cryogenic liquid and vapor applications including oxygen, nitrogen, argon, carbon dioxide and other compatible gases.
