Rheem rcexv-hf0000000-02 Thermostatic Expansion Valve

Product Description

The RHEEM rcexv-hf0000000-02 is a thermostatic expansion valve (TXV) designed to meter refrigerant flow into the evaporator coil of a split-system or packaged HVAC unit. The TXV responds to suction line superheat, modulating refrigerant feed to maintain optimal evaporator performance across varying load conditions. This type of metering device replaces fixed orifice pistons in systems that require closer refrigerant control, and is typically installed by a licensed HVAC technician during system commissioning, coil replacement, or refrigerant system servicing.

This valve is intended for use in residential or light-commercial RHEEM cooling systems where a factory-matched TXV is specified. A TXV is commonly installed at the inlet of the indoor evaporator coil, with the sensing bulb clamped to the suction line near the coil outlet. Proper bulb placement and insulation are critical to accurate superheat sensing and stable system operation. Consult the equipment installation manual for the specific coil or air handler this valve is paired with.

Key Features

• Factory RHEEM replacement TXV for precise refrigerant metering
• Responds dynamically to suction line superheat for load-following control
• OEM-matched design supports proper system efficiency ratings
• Sold as a single unit for direct replacement service work

Compatibility

Designed as an OEM-style replacement thermostatic expansion valve for RHEEM residential and light-commercial split-system or packaged cooling equipment. Consult the equipment model documentation or RHEEM technical support to confirm fitment for a specific coil or system configuration before installation.

Installation Notes

TXV replacement should be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before opening any refrigerant circuit connections. After installation, evacuate the system to a deep vacuum before recharging, and verify suction line superheat at the sensing bulb location to confirm correct valve operation. Follow all applicable local mechanical codes and the equipment manufacturer installation instructions.
