Nordyne Intertherm 920670a Txv Valve R-410A 3 Ton

Product Description

The NORDYNE INTERTHERM 920670a is a thermostatic expansion valve (TXV) designed for use with R-410A refrigerant in 3-ton cooling systems. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level to maximize system efficiency and protect the compressor from liquid slugging. This valve is an OEM-specification component suited for residential split-system air conditioners and heat pumps. Licensed HVAC technicians handle installation and service of this component as part of a sealed refrigerant circuit.

This TXV is rated for R-410A refrigerant at a 3-ton capacity, making it appropriate for residential split-system applications where precise refrigerant metering is required. It is installed at the indoor evaporator coil assembly, typically as a replacement for a failed or underperforming expansion device. Installations are found in residential forced-air cooling and heat pump systems where maintaining correct superheat across the evaporator is critical to system performance and equipment longevity.

Key Features

• Rated for R-410A refrigerant, compatible with current HFC-based residential systems
• 3-ton capacity for standard residential cooling applications
• OEM-specification design for direct replacement in applicable NORDYNE INTERTHERM equipment
• Controls refrigerant superheat to protect the compressor and optimize evaporator performance

Compatibility

Designed as an OEM-style replacement TXV for NORDYNE INTERTHERM residential split-system air conditioners and heat pumps using R-410A refrigerant at 3-ton capacity.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician, as this component is part of a sealed refrigerant circuit. Recover all refrigerant from the system before removing the existing valve. After installation, evacuate the system to the required vacuum level before recharging with R-410A to manufacturer specifications. Verify superheat readings at startup to confirm correct valve operation.
