Copeland 910-0352-02 Valve & Coil

The Copeland 910-0352-02 Valve & Coil is a critical field-service component engineered specifically for Demand Cooling systems on Copeland Discus semi-hermetic compressors. Designed to mitigate high discharge temperatures—a common failure point in low-temperature refrigeration applications using R-22, R-407A/C/F, or R-448A/449A—this demand cooling solenoid valve provides precise liquid injection to maintain the compressor within safe operating thermal limits. The assembly includes a 120V replacement solenoid coil and a high-durability valve body featuring a brazed connection (sweat) inlet and a flare outlet for direct integration into the compressor head injection port.

When the Demand Cooling module detects discharge temperatures exceeding 292°F via the thermistor, it energizes this 120V coil to inject a metered amount of saturated refrigerant into the suction chamber. This phase change absorbs excess heat, protecting internal components from carbonization and oil breakdown. As an authentic OEM Copeland 910-0352-02 part, this kit ensures the exact flow coefficient (Cv) required for 3D and 4D compressor body styles, preventing the over-saturation or "icing" issues often found with generic universal alternatives.

• Thermal Protection: Prevents lubricant "coking" and discharge valve failure by maintaining head temperatures below 225°F.
• System Compatibility: Pre-configured for 120V refrigeration controls and optimized for Copeland 3DF3A090E-TFD and similar Discus models.
• Rugged Construction: Bi-metal composition with robust seat materials designed to withstand high-cycle liquid injection demands.
• Direct Fitment: Includes both the solenoid coil and valve body, ensuring a complete seal and reducing leak points during a retrofit or repair.
• Refrigerant Versatility: Suitable for modern low-GWP HFO blends and legacy HCFC systems requiring active cooling.

What are the signs that a Demand Cooling valve has failed?
If you find the compressor head heavily iced over, the valve is likely stuck open. Conversely, if you see "High Discharge Temp" trips on the module despite having power at the 120V coil, the valve orifice may be clogged or the plunger seized.

Is a filter drier required for this installation?
Yes. To protect the precision orifice of the Copeland 910-0352-02, always install a dedicated liquid line filter drier (capable of 25-micron filtration) in the injection line upstream of the valve inlet.

Can this valve be used on any semi-hermetic compressor?
No, this is specifically for Copeland Discus compressors equipped with injection ports. Always verify your compressor's model number and control voltage before installation.
