Copeland 998-1661-27 Valve Plate

The Copeland 998-1661-27 Valve Plate is a high-performance replacement valve plate kit specifically engineered for Copeland 4D, 6D, and 8D Discus compressors. Designed for standard bank, non-unloader applications, this assembly utilizes floating suction reed technology to maintain optimal volumetric efficiency. In the field, technicians rely on this refrigeration compressor part for its ability to restore proper compression ratios and mitigate discharge temperature issues caused by worn internal components. This kit is built with heavy-duty steel valve plate construction, ensuring it can withstand a pressure range up to 350 PSI and a temperature range of -20°F to 130°F. The assembly includes the precision-machined valve plate, suction reeds, pins, and essential gaskets to ensure a leak-proof seal during refrigerant flow control. Whether you are servicing a commercial HVAC rack or an industrial chiller, the 998-1661-27 provides the tight tolerances required for long-term reliability in demanding environments.

• Compatible with a wide range of Copeland Discus models, including 4DL, 6DH, and 8DP series.
• Features floating suction reed design for improved efficiency compared to traditional rigid reed setups.
• Comprehensive kit includes all necessary hardware and gaskets for a complete head-to-cylinder seal.
• Constructed from industrial-grade steel to resist warping under high-cycling thermal loads.
• Maintains precise refrigerant flow for consistent cooling capacity and oil return.

• Which compressor models use the 998-1661-27? This kit is compatible with most 4D, 6D, and 8D Discus compressors; however, it is specifically for 1.5" and Standard Bank non-unloading heads.
• Does this kit include the discharge and suction reeds? Yes, the assembly typically includes the internal reed components and the required mounting pins for installation.
• Can this be used with both R-22 and R-404A systems? Yes, the materials are compatible with standard HCFC and HFC refrigerants and their associated POE or Mineral oils.
