Copeland 910-0351-00 Valve

The Copeland 910-0351-00 is an essential Demand Cooling Valve designed for Copeland Discus compressors operating in low-temperature refrigeration environments. As a veteran technician knows, maintaining proper discharge temperatures is critical when running refrigerants like R-404A, R-407A, or R-448A/R-449A. This liquid injection valve functions by metering saturated refrigerant into the suction cavity when the CoreSense or Demand Cooling module detects high discharge head temperatures. By mitigating thermal stress, the 910-0351-00 solenoid valve prevents oil breakdown and ensures the long-term reliability of the compressor cylinder head components during high compression ratio cycles. This genuine Copeland OEM part is engineered for precision flow control, minimizing pressure drop while maximizing heat transfer efficiency within the evaporator circuit. Designed for rugged commercial and industrial duty, it features a robust 5.5-inch body and is compatible with standard 120V or 240V solenoid coils depending on the specific system configuration. Proper installation requires ensuring sufficient liquid subcooling at the valve inlet to prevent premature flashing and erratic cooling performance.

• Active Thermal Protection: Automatically regulates internal temperatures to prevent compressor overheating during low-suction, high-head pressure scenarios.
• OEM Compatibility: Specifically engineered as a direct replacement for Copeland 910-0351-00 systems, ensuring correct fitment and flow rates for Discus compressors.
• Enhanced System Reliability: Guards against carbonization of valves and oil sludge by maintaining discharge gas within safe operating limits.
• Precise Refrigerant Metering: Highly accurate internal needle and orifice design provides consistent cooling without unnecessary refrigerant bypass.

• When is a Demand Cooling Valve required? It is typically necessary for low-temperature R-404A applications or when using newer HFO blends where discharge temperatures naturally exceed safe limits.
• Can this valve be field-serviced? While the solenoid coil is replaceable, the internal valve body is a precision-calibrated component; if the injection port fails to frost during operation, the entire valve unit usually requires replacement.
• Is the temperature sensor included? This SKU (910-0351-00) refers to the Demand Cooling Valve itself; the discharge temperature probe and electronic control module are often sold separately or as part of a complete kit.
