Copeland 998-1000-52 DTC Valve & Thermostat Kit 120/240V

The Copeland 998-1000-52 Discharge Temperature Control (DTC) Valve and Thermostat Kit is designed specifically for ZF13KVE-T, ZF18KVE-T, ZF25KVE-T, and ZF28KVE-T compressor models. This kit regulates the temperature of discharged refrigerant gas by injecting liquid refrigerant back into the compressor housing, providing essential protection for low-temperature refrigeration applications.

Complete Kit Components:

• DTC Valve with 250°F set point
• 260°F thermostat for 5/8" discharge lines
• 260°F thermostat for 3/4" discharge lines
• T-Fitting for vapor injection applications
• Spring-coil thermistor, thermal grease, Rotalock fitting seals, and installation instructions

This kit includes replacement parts engineered to match original Copeland compressor specifications, ensuring compatibility and reliable operation while regulating refrigerant flow and maintaining appropriate temperatures. The discharge line thermostat works with either 120V or 240V supply, providing flexible installation options for various electrical configurations.

High discharge temperature protection should always be fitted to each compressor to ensure it cannot overheat in the event of loss of liquid or vapor injection cooling. This kit is essential for maintaining compressor integrity and preventing damage in demanding refrigeration applications including supermarkets, restaurants, and convenience stores.
