NTI Gas Valve for Trinity Boilers

The NTI gas valve (also called a boiler gas control valve or gas regulator valve) is a genuine replacement part for NTI Trinity condensing gas boilers. It controls and regulates the flow of fuel to the burner, so the boiler can light reliably and modulate its output during heating cycles.

Key Features:

• Manufactured or specified by NTI (Ariston Group) for use in the Trinity boiler line
• Meters gas to the premix burner and works with the venturi to keep the air/fuel ratio consistent
• Designed to support the efficient, modulating combustion of Trinity condensing boilers
• Replaces a worn or failed original valve to restore normal boiler operation
• Related installation parts, such as gas valve adapters, harnesses, orifices and inlet O-rings, are available separately

The product line includes gas valves for several Trinity boiler series. Choose the valve that matches the part number of the original on your boiler. Gas valve replacement should be done by a qualified heating technician, following the NTI service instructions and local codes.
