Pressure-Regulating Valves for Fuel Gases
- For Use With: See Table
- 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.
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.

Tank-Mount Pressure-Regulating Valves for Fuel Gases
- For Use With: See Table
- Temperature Range: -20° to 120° F
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.

Pipeline Flame Arresters
- For Use With: Butane, Natural Gas, Propane
- Flame-Arresting Element Material: 316 Stainless Steel
To prevent flashback in flammable gas pipelines, an internal flame-arresting element absorbs the heat from a fire to extinguish the flame. These valves are commonly used in pilot lines connected to waste gas burners.

On/Off Valves with 45° Flared Compression
Fittings for Natural Gas, Propane, and Butane
- Valve Type: Ball
- For Use With: Butane, Natural Gas, Propane
- Seal Material: PTFE Plastic
- Specifications Met: CSA Certified, CSA-US Certified, UL Listed
With 45° flared tube fittings, these valves form a tight seal on metal tubing lines for natural gas, propane, and butane. All have a T-handle that resists accidental movement when snagged or bumped. Valves are standard port, so they slightly restrict flow.
