Reznor 89351 Modulating Gas Valve - 1-1/4 Inch

The Reznor 89351 is a 1-1/4 inch modulating gas valve designed for use with Reznor heating equipment including direct-fired and indirect-fired unit heaters, duct furnaces, and makeup air systems. This OEM replacement valve provides precise gas flow control for applications requiring variable heat output and consistent temperature maintenance.

Key Features:

• 1-1/4 inch NPT connection size for high-capacity heating applications
• Modulating control allows continuous flame adjustment for precise temperature control
• Designed for use with Reznor electronic modulation systems including 6:1 turndown configurations
• Compatible with natural gas and propane applications
• Operates with 24-volt control systems
• Used in Reznor RDCA/RDDA and ADFH series equipment

This modulating valve is a critical component in systems requiring efficient, variable-output heating control. It works in conjunction with electronic controllers and amplifiers to provide instantaneous response to temperature changes without the need for mechanical butterfly valves or external activation. Commonly used as part of multi-valve gas train configurations on larger commercial and industrial heating units.
