REGO PRV19434TP150 1/2″ Brass ASME Cryogenic Relief Valve 150 PSI O2 Clean

Overview

The T in the part number identifies the PTFE seat, while the P specifies the no-drain-hole configuration. REGO specifies PTFE for 140–600 PSIG set points.

Product Description

The REGO PRV19434TP150 is an ASME-rated cryogenic pressure relief valve designed for oxygen and other compatible industrial-gas applications. It features a durable brass body, 1/2″ NPT inlet, PTFE softgoods, stainless-steel spring trim, and a factory pressure setting of 150 PSIG.

This particular TP150 configuration is supplied without a drain hole and without a pipe-away adapter. The valve is designed for cryogenic vapor-space service and may be applied to appropriate piping systems, liquid cylinders, and mini-bulk cryogenic containers requiring an ASME relief device.
