Midwest Hearth’s gas valve kit is a CSA-certified, heavy-duty 3/4" NPT solid brass ball valve assembly with a flat black floor plate and key, rated to 300,000 BTU for both natural gas and propane.

If you’re outfitting a new fire pit, replacing a tired control valve, or upgrading an outdoor kitchen gas line, you need a reliable, high-capacity valve that meets North American safety rules. This kit from Midwest Hearth includes the valve, a decorative flat black floor plate, and a universal key designed to match common gas fire features. Built from solid brass and certified to ANSI/CSA standards, it’s sized and specified for powerful fire applications while remaining straightforward to install for professionals and experienced DIYers.

How does this valve kit ensure safety and compliance?

The kit carries ANSI Z21.5 / CSA certification, meaning it has been independently tested for use with residential and commercial gas appliances. Certification reduces guesswork during inspections and helps meet local code expectations when you install a gas fire feature.

• CSA certified to North American standards
• Tested for both natural gas and liquid propane use
• Manufactured to consistent quality tolerances
• Intended for both residential and commercial installations

What are the flow and pressure capabilities of the valve?

This solid brass ball valve is rated at 300,000 BTU and accepts up to 1/2 PSIG maximum pressure, delivering high flow for large burners, fire pits, and other high-output features. The 3/4" NPT inlet and outlet help maintain minimal pressure drop for better flame performance.

• 300,000 BTU capacity for high-output systems
• 3/4" NPT inlet and outlet for robust flow
• 1/2 PSIG maximum working pressure
• Quarter-turn ball design for quick, positive shutoff

What exactly comes in the kit and how does it fit visually?

The package includes a straight solid brass ball valve, a flat black floor plate, and a 3" universal Zamak die-cast key. The flat black finish gives a low-profile, finished look that complements stone, metal, and concrete surrounds without drawing attention away from the feature.

• Solid brass straight ball valve included
• Flat black floor plate for a clean, decorative opening
• 3" universal key for easy operation and compatibility
• Finished aesthetic for indoor or outdoor installations

Are there any important installation notes I should know?

Yes. The valve inlet/outlet threads are 3/4" NPT, while the floor plate and the valve stem thread interface use 1/2" NPSM—this is standard for keyed valve kits and not a defect. Make sure your contractor or installer is aware of the thread types to select the correct fittings and adapters.

• Valve: 3/4" NPT inlet/outlet
• Floor plate/key connection: 1/2" NPSM threads
• Quarter-turn operation requires minimal torque
• Professional installation recommended for compliance

If you need a dependable brass ball valve that supports both natural gas and propane, meets safety standards, and delivers strong BTU capacity for large burners or fire pits, this Midwest Hearth kit is designed for that purpose.
