Attach these valves to acetylene, hydrogen, methane, propane, or propylene tanks to reduce a high inlet pressure to a lower, stable outlet pressure. They have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves come with a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.

Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.

Valves with a brass body have a longer service life than valves with a brass and steel body.

Temperature Range: See Table

Install these valves directly in gas distribution pipelines for acetylene, hydrogen, or propane. They automatically reduce a high inlet pressure to a lower, stable outlet pressure. Valves have two outlets to fit various pipe configurations and come with a plug to close the unused outlet. The gauge monitors outlet pressure. All valves are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate.
