Reznor 220552 Expansion Valve

Secure precise refrigerant metering for high-performance commercial cooling with the Reznor 220552 Thermal Expansion Valve. As an authentic Reznor OEM part, this Thermostatic Expansion Valve (TXV) is engineered specifically for R-410A systems, featuring a 1/2-inch inlet and a 5/8-inch outlet for seamless integration. The BBIZE-2 - ZGA assembly utilizes a sensing bulb and capillary tube mechanism to maintain optimal superheat, preventing liquid slugging and protecting the compressor from premature failure. Designed for durability in demanding environments, this HVAC replacement part ensures your rooftop unit or air handler operates at peak efficiency by adjusting the mass flow of refrigerant in real-time response to evaporator load changes. It serves as a direct drop-in replacement for worn or restricted refrigerant metering devices across a wide range of Reznor PDH, RDDC, and ACUA series equipment, maintaining the mechanical integrity and thermal performance required by veteran contractors.

• OEM Compatibility: Specifically designed to replace Reznor part 220552 in models like PDH 75-300 and ACUA 60 without field modifications.
