Rheem 61-109537-21v Expansion Valve Txv

Product Description

The RHEEM 61-109537-21v is a thermostatic expansion valve (TXV) sold as a valve-only replacement component for refrigerant metering in split-system and packaged HVAC equipment. The TXV regulates refrigerant flow into the evaporator coil by responding to suction-line superheat, maintaining the correct refrigerant feed rate across varying load conditions. This part is sold without associated fittings or bulb hardware unless otherwise noted. Licensed HVAC technicians perform this replacement as part of refrigeration circuit service or coil changeouts.

This TXV is intended for use in refrigerant metering applications on RHEEM residential or light-commercial cooling and heat pump systems where this part number is specified. The valve-only format makes it appropriate for scenarios where existing fittings, sensing bulbs, or external equalizer lines are being reused from the original assembly. Verify the application and system refrigerant type against the equipment nameplate before installation.

Key Features

• Thermostatic expansion valve design meters refrigerant flow based on evaporator superheat
• Valve-only configuration allows reuse of compatible existing hardware
• OEM RHEEM part number ensures correct fit for specified equipment
• Sold individually as a single unit replacement component

Compatibility

Designed as an OEM-style replacement TXV for RHEEM refrigeration circuit applications where part number 61-109537-21v is specified by the equipment manufacturer.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all system refrigerant before opening the refrigeration circuit and follow all applicable local and national mechanical codes. The system must be evacuated and leak-tested after valve replacement before recharging with refrigerant. Do not reuse refrigerant that has been contaminated.
