Danfoss 068-200300 Txv Orifice Cartridge T2

Product Description

The DANFOSS 068-200300 is a T2 orifice cartridge designed for use with Danfoss thermostatic expansion valves (TXV). The orifice cartridge meters refrigerant flow into the evaporator, directly controlling superheat and system efficiency. This component is sized for light-capacity applications and is compatible with multiple common refrigerants. Licensed HVAC technicians install and service this part during TXV rebuilds, capacity changes, or refrigerant conversions on split systems and packaged equipment.

This T2 orifice cartridge is rated for use with R22 at 1/3 ton, R134A at 1/4 ton, and R404A/R507 at 1/5 ton. It is intended for small-tonnage refrigeration and air conditioning systems where precise refrigerant metering at low capacity is required. Typical applications include light commercial refrigeration cases, small split system air conditioners, and reach-in cooler circuits using any of the supported refrigerant types.

Key Features

• T2 orifice size suited for low-capacity refrigerant metering in TXV assemblies
• Compatible with R22 (1/3 ton), R134A (1/4 ton), and R404A/R507 (1/5 ton)
• Designed as a serviceable cartridge for field replacement without full valve changeout
• Supports multiple refrigerant types, useful for systems undergoing refrigerant transitions
• Compact and lightweight for easy handling in tight equipment compartments

Compatibility

Designed as an OEM-style replacement orifice cartridge for Danfoss TXV valves requiring a T2 orifice. Compatible refrigerants include R22, R134A, R404A, and R507 at the capacities stated above. No additional model-specific compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a licensed HVAC technician holding the appropriate EPA Section 608 refrigerant handling certification. Recover all system refrigerant and relieve system pressure before removing or replacing the orifice cartridge. Verify the replacement orifice size and refrigerant rating match the system requirements before installation. After reassembly, leak-check all valve connections and recharge the system to manufacturer specifications before returning it to service.
