Buying Guide
What should you consider when choosing a 24V gas valve?
- Compatibility with equipment: Check port sizes (often 1/2″ or 3/4″), inlet/outlet arrangement, and electrical coil voltage to match your furnace or boiler.
- Ignition type: Direct ignition valves work quickly but may demand precise control wiring; intermittent pilot valves provide reliability with lighter wiring requirements.
- Gas type support: Ensure the valve supports natural gas, propane, or both, depending on your appliance’s gas supply.
- OEM vs aftermarket: OEM parts typically guarantee fit and function for specific brands, but aftermarkets can offer cost savings with comparable performance.
- Installation complexity: Some valves are straightforward replacements; others require wiring and control board compatibility checks.
- Safety and compliance: Use valves rated for your appliance’s BTU rating and ensure proper venting and gas connections.
