Carrier 332368-761 Thermal Expansion Valve Kit

The Carrier 332368-761 Thermal Expansion Valve Kit is a precision-engineered genuine OEM replacement designed to modulate refrigerant flow and maintain precise superheat control in 4-ton high-efficiency cooling systems. Manufactured by Danfoss (Model EA36YD162, Type TR6), this thermostatic expansion valve (TXV) is specifically calibrated for R-410A refrigerant, ensuring stable evaporator performance even under fluctuating load conditions. This factory-authorized part replaces legacy numbers EA36YD311 and EA36YD162, providing a direct-fit solution for Carrier, Bryant, and Payne residential fan coils and central air conditioners.

Built with a stainless steel sensing bulb and featuring an externally equalized design, this valve offers superior durability against corrosion and reliable pressure regulation up to 660 psig. The kit includes a 3/8-inch sweat inlet and 3/8-inch threaded outlet for secure integration into the liquid line. By preventing evaporator flooding and compressor slugging, this 4-ton TXV kit restores system SEER ratings and protects the compressor’s long-term mechanical integrity. For professional contractors, choosing this Carrier-approved valve ensures seamless compatibility with FX4D, FB4C, and PF4M series units without the need for field modifications.

• Precise Refrigerant Metering: Delivers exact R-410A flow to the evaporator coil to maximize heat exchange efficiency.
• OEM Compatibility: Guaranteed fit for Carrier, Bryant, and Payne 4-ton air handlers and heat pumps, including the FB4C and PF4M series.
• Heavy-Duty Construction: Features a stainless steel sensing bulb and robust valve body rated for a Maximum Working Pressure (MWP) of 660 psig.
• Critical System Protection: Controls evaporator superheat to prevent liquid refrigerant from returning to the compressor.
• Complete Installation Kit: Includes the 332368-761 valve, bulb mounting strap, teflon O-ring, and installation instructions for streamlined service calls.
