Carrier 06DA660175 Control Valve

The Carrier 06DA660175 Electric Unloader Control Valve is a critical OEM replacement component engineered for precise refrigerant flow regulation and compressor capacity modulation. As a direct replacement for the obsolete 06EA660135, this valve is designed to integrate seamlessly with Carrier 06D and 06E semi-hermetic compressors. It utilizes a 24V DC magnetic drive mechanism to actuate unloading cycles, shifting the compressor based on actual load demand to prevent short-cycling and reduce energy consumption. For technicians performing HVAC compressor troubleshooting, this capacity control valve ensures stable suction pressures and maintains tight temperature tolerances in commercial refrigeration and air conditioning systems. Built with a rugged housing and a reliable inlet check and relief valve assembly, the 06DA660175 provides the mechanical durability required for high-cycle industrial environments, maximizing HVAC system efficiency through accurate electrical actuation.

• Direct OEM Compatibility: Serves as the factory-authorized replacement for the 06EA660135, ensuring a perfect fit without field modifications.
• Precise Modulation: Features an electric unloader design that enables active compressor capacity control for improved system stability.
• Energy Optimization: Reduces power draw by unloading cylinders during low-load conditions, lowering overall operational costs.
• Rugged Reliability: Constructed with a magnetic drive and an adjustable spring assembly for consistent performance under high-pressure refrigeration cycles.

Is the 06DA660175 a direct drop-in for the 06EA660135?
Yes, this electric unloader control valve is the manufacturer-specified replacement for the 06EA660135 and is designed to fit the existing mounting footprint on Carrier 06E compressors.

What are the symptoms of a failing unloader control valve?
Common indicators include the compressor failing to load/unload properly, erratic suction pressures, or the system operating continuously in a high-capacity state regardless of demand.

Does this valve require a specific voltage for actuation?
The 06DA660175 is typically powered by a 24V DC motor or solenoid coil; always verify your control circuit voltage against the specific compressor nameplate and wiring diagram before installation.
