Copeland PLT-1625 Valve Plate Assembly 4D 6D 8D

Product Description

The COPELAND PLT-1625 is a disc type valve plate assembly designed for use in Copeland reciprocating compressors. It replaces the valve plate assembly as part of the compressor unloading system, providing precise gas flow control through a floating suction reed and low-temperature unloading bank configuration. This assembly is a direct OEM-style replacement that restores compressor function in low-temperature refrigeration applications. HVAC and refrigeration technicians performing compressor rebuilds or valve plate replacements will find this part matches the original design intent and fits the targeted compressor models.

This valve plate assembly is intended for low-temperature refrigeration applications where precise suction reed action and reliable unloading performance are critical to system efficiency. It is suited for commercial refrigeration systems using Copeland 4D, 6D, and 8D series reciprocating compressors. The disc type valve design supports controlled unloading bank operation, making it appropriate for systems that cycle between loaded and unloaded compression stages in low-temperature service environments.

Installation Notes

Installation should be performed by a licensed refrigeration or HVAC technician. Recover all system refrigerant and relieve system pressure before opening the compressor. Inspect valve seat surfaces and mating gaskets before installing the new valve plate assembly to ensure a proper seal. Follow compressor manufacturer service procedures and applicable local codes when reassembling and recharging the system.
