Ducane 25W28 Thermostatic Expansion Valve

Product Description

The DUCANE 25W28 is a thermostatic expansion valve (TXV) designed to regulate refrigerant flow in refrigeration systems. The TXV meters liquid refrigerant into the evaporator coil based on superheat, maintaining efficient heat transfer and protecting the compressor from liquid slugging. At 0.93 pounds and compact in size, this valve is suited for installation in tight equipment cabinets or line sets. HVAC and refrigeration technicians install this component as part of routine system service or refrigerant-side repairs where precise flow control is required.

This thermostatic expansion valve is intended for use in refrigeration applications. It is sized and configured for systems where a TXV is specified as the metering device. Service technicians replacing a failed or underperforming expansion valve will find this a direct OEM-style replacement. Refer to system engineering documentation to confirm valve capacity rating and bulb charge type match the target application before installation.

Key Features

• Thermostatic expansion valve designed for refrigeration system metering duty
• Regulates refrigerant flow based on evaporator outlet superheat
• Compact form factor at 4.5 inches long, 3.5 inches wide, and 3.0 inches tall
• Lightweight at 0.93 pounds for easier handling in confined install spaces
• OEM part number 25W28 for direct sourcing and replacement verification

Compatibility

Designed as an OEM-style replacement thermostatic expansion valve for refrigeration systems where the DUCANE 25W28 is the specified metering device.

Installation Notes

TXV replacement is performed by a licensed HVAC or refrigeration technician. The system must be recovered of refrigerant per EPA Section 608 requirements before removing the existing valve. Braze or flare connections should be made with the appropriate tools and fittings per manufacturer specifications. After installation, the system must be leak-tested, evacuated, and recharged before returning to service.
