Diversitech TXVH-04 Txv Replacement Capacity Cartridge

Product Description

The DIVERSITECH TXVH-04 is a capacity cartridge designed for use with TXVH and TXVHE series thermostatic expansion valves. TXV cartridges regulate refrigerant flow into the evaporator coil by responding to suction line temperature and pressure, maintaining the correct superheat setting across varying load conditions. This cartridge is a direct-fit replacement component, allowing technicians to service an existing valve body without replacing the entire assembly. HVAC refrigeration technicians install this part during system maintenance or when correcting superheat issues traced to a worn or failed cartridge.

This cartridge is suited for refrigeration and air conditioning systems where TXVH or TXVHE valve bodies are already installed. It is used in both residential and light commercial HVAC applications where precise refrigerant metering is required. When a system presents symptoms such as improper superheat, flooding, or starved evaporator conditions, replacing the cartridge is a targeted repair that restores valve performance without full valve replacement.

Key Features

• Direct-fit capacity cartridge for TXVH and TXVHE valve bodies
• Restores proper refrigerant metering and superheat control
• Allows cartridge-only replacement without removing the full valve assembly
• Compatible with refrigeration and air conditioning system applications

Compatibility

Designed for use with TXVH and TXVHE series thermostatic expansion valves.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. Recover all system refrigerant and ensure the system is fully depressurized before removing the existing cartridge. Follow the valve manufacturer's torque and installation guidance when seating the new cartridge to prevent leaks. Recheck system superheat after recharging to confirm proper valve operation.
