Product Description

REGO B-19434B250 1/2″ Brass Cryogenic Gas Relief Valve – 250 PSIG

This genuine REGO B-19434B250 pressure relief valve is designed for compatible cryogenic gas and industrial gas applications. It features a 1/2″ male NPT inlet, 1/2″ female NPT outlet, brass body and a 250 PSIG factory-set pressure.

The B-19434B Series is suitable for oxygen and non-corrosive industrial gases such as nitrogen, argon and helium. The valve is cleaned for oxygen service per CGA G-4.1 and is ASME rated/certified.

The valve is designed to initially open slightly to relieve moderate overpressure and then open to full discharge capacity as pressure increases. REGO specifies bubble-tight performance at 95% of set pressure and full flow at 110% of set pressure.
