Description

REGO CG500B 1/2″ Brass Inline Cryogenic Check Valve – Metal Seat – 3000 PSIG – O2 Cleaned

The REGO CG500B is a heavy-duty inline check valve engineered for gas and cryogenic service. It features a durable ASTM B16 brass body with a 303 stainless-steel metal seat, making it suitable for demanding low-temperature applications.

The valve has 1/2″ FNPT female inlet and outlet connections and provides one-directional flow, with the proper flow direction indicated by an arrow on the valve body. Its high-flow design provides a Cv of 3.5, helping minimize pressure drop through the system.

The CG500B is rated for a maximum operating pressure of 3,000 PSIG and has a low 1 PSIG cracking/opening pressure. Its metal-seat construction provides a broad operating temperature range of -320°F to +165°F (-195°C to +74°C).

The valve is also cleaned for oxygen service per CGA G-4.1, making it appropriate for compatible oxygen and cryogenic applications when installed and operated according to applicable safety requirements.
