Copeland 998-0500-03 Valve Kit

The Copeland 998-0500-03 Valve Kit is a critical Discharge Temperature Control (DTC) valve assembly engineered for high-performance Copeland Scroll compressors. As a veteran-grade OEM replacement part, this kit is specifically designed to manage liquid injection, protecting the compressor from extreme discharge temperatures during low-evaporating temperature operations. It is widely utilized in ZF, ZFD, and ZF*KVE scroll models running R-404A, R-407A/C/F, R-448A, and R-449A refrigerants. The DTC valve kit ensures the compressor stays within its safe operating envelope by sensing discharge heat and modulating refrigerant flow to keep the internal assembly cool. By maintaining precise refrigerant control, this kit prevents oil breakdown and component fatigue, ensuring long-term reliability for commercial refrigeration and industrial cooling systems.

• Thermal Protection: Precisely modulates liquid injection to prevent compressor overheating and maintain discharge temperatures below critical levels.
• System Compatibility: Engineered for seamless integration with Copeland ZF series scroll compressors, ensuring a perfect fit and factory-spec performance.
• Durable Construction: Features high-grade brass and stainless steel components designed to withstand the rigors of industrial HVACR environments.
• Comprehensive Kit: Includes the DTC valve, discharge line thermostat, bulb, and mounting hardware for a complete field service solution.

Which refrigerants are compatible with the 998-0500-03 kit?
This kit is optimized for systems utilizing R-404A, R-407A, R-407C, R-407F, R-448A, and R-449A. Always verify your specific compressor model number before installation.

What happens if the DTC valve is not installed correctly?
Failure to ensure liquid refrigerant is available at the valve inlet prior to startup can lead to valve chatter or internal compressor damage. Ensure the bulb is seated with thermal grease for accurate sensing.

Can I use this kit on any scroll compressor?
No, this DTC Valve Kit is specific to models designed with a liquid injection port. Check the technical manual to confirm your Copeland compressor supports the DTC injection method.
