Product Description

REGO B-840-12T 1-1/2″ Bronze Cryogenic Swing Check Valve – Soft Seat

The REGO B-840-12T is a heavy-duty 840 Series bronze swing check valve designed to prevent reverse flow in compatible cryogenic and industrial gas systems.

This model features 1-1/2″ FNPT threaded ends, a soft seat and a 0.5 PSIG cracking pressure. The 840 Series is rated for 400 PSIG cold, non-shock working pressure and is designed for low-temperature service down to approximately -325°F.

The valve uses a top-entry design, allowing it to be serviced from above while permanently installed in the piping system. Its swing-check construction provides relatively high flow capacity compared with poppet or lift-style check valves.
