Overview

he exact PRV19434TP175 is specified by a current distributor as a 1/2-inch brass, 175-PSIG ASME valve with PTFE softgoods, no drain hole, and no pipeaway adapter.

Product Description

The REGO PRV19434TP175 is an ASME-rated pressure relief valve engineered for cryogenic and industrial gas vapor service. It features a rugged brass body, stainless-steel spring trim, PTFE softgoods, and a 1/2″ inlet connection.

This valve is factory set at 175 PSIG and is designed to protect cryogenic piping, liquid cylinders, mini-bulk containers, and similar equipment against excessive vapor pressure. REGO specifies PTFE for 19430 Series set pressures from 140–600 PSIG, making PTFE the specified seat material for this 175-PSIG configuration.

The “P” designation in this part number identifies the no-drain-hole configuration. This particular model is also supplied without a pipeaway adapter.
