    About Pressure-Regulating Valves
    industrial info icon

    Find a regulator that’s compatible with your gas, matches the CGA number on your tank, and has twice the operating pressure of your application’s normal range.

    Tank-Mount Pressure-Regulating Valves for Fuel Gases

    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.

    Valve With Knob

    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.

    Inlet Two-Stage Valve

    With T-Handle

    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.
