REGO PRV9434T350 1/2″ Brass Cryogenic Relief Valve 350 PSI PTFE O2 Clean

Product Specifications

Product Description

The REGO PRV9434T350 is a 9400 Series cryogenic pressure relief valve designed for pressure protection in industrial gas and cryogenic vapor systems.

This configuration features a rugged brass body, 1/2″ male NPT inlet, PTFE seat/softgoods, stainless-steel spring components, and a factory-calibrated relief setting of 350 PSIG.

The PRV9434T350 includes a drain hole and does not include a pipe-away adapter. It is also O2 cleaned for appropriate oxygen-service applications.

Its compact construction makes it suitable for cryogenic containers, vapor piping and industrial gas equipment where reliable automatic overpressure protection is required.
