Rheem 611048a Txv Expansion Valve Bleed Port Check Valve R410A

Product Description

The RHEEM 611048a is a thermostatic expansion valve (TXV) engineered for use with R-410A refrigerant systems. It incorporates a bleed port and an integral check valve into a single assembly, allowing the valve to perform both metering and reverse-flow functions without additional components. The bleed port ensures pressure equalization across the system during the off cycle, supporting reliable compressor restart. This valve is installed by licensed HVAC technicians during new equipment installation or refrigeration-side service on split-system cooling equipment.

This TXV is suited for residential and light commercial split-system air conditioning and heat pump applications using R-410A refrigerant. The integrated check valve eliminates the need for a separate field-installed check valve in the liquid line, simplifying the refrigerant circuit. Typical installation scenarios include indoor coil replacement, refrigerant-circuit repairs, and system upgrades from older refrigerant types where a compatible metering device is required.

Key Features

• Compatible with R-410A refrigerant for use in current-generation split systems
• Integrated bleed port allows pressure equalization during compressor off cycle
• Built-in check valve supports bidirectional refrigerant flow without a separate field component
• Single-assembly design reduces installation complexity and potential leak points
• OEM-style form factor for straightforward replacement fitment

Compatibility

Designed as an OEM-style replacement thermostatic expansion valve for R-410A split-system air conditioning and heat pump equipment.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before opening the refrigerant circuit, in compliance with EPA and local regulations. Confirm valve orientation and flow direction markings before brazing or connecting fittings, as reversing the valve will prevent proper system operation. After installation, leak-check all connections and recharge the system to manufacturer specifications before returning the equipment to service.
