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.

Single Stage


Male Outlet × Male Inlet Single-Stage Valve With T-Handle	Male Outlet × Male Inlet Single-Stage 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.

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

Stainless Steel Diaphragm—Valves with a stainless steel diaphragm can withstand harsh environments.

Two Stage

Male Outlet × Male

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.

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

Stainless Steel Diaphragm—Valves with a stainless steel diaphragm can withstand harsh environments.
