Description
The RegO 597FA is part of the RegO 597F Series of high-pressure industrial and commercial pounds-to-pounds LPG regulators.
It is designed to reduce propane container pressure to a controlled downstream pressure and is suitable for both liquid and vapor service. RegO specifies the 597F Series for applications including industrial heating equipment and other commercial or industrial LPG services.
The 597FA model uses a T-handle adjustment mechanism, 1/4″ F.NPT inlet and outlet connections, and provides a compact configuration for installation where adjustable high-pressure LPG regulation is required.

Important Installation Note
The regulator must be selected and installed according to the actual LPG system design, required flow rate, inlet pressure, outlet pressure and applicable safety requirements.
Do not select a regulator based only on pipe size. Gas demand, operating pressure, regulator capacity and system configuration should be considered by a qualified engineer/installer.
RegO’s documentation also specifies the operating conditions associated with its published capacity figures.
