Expansion Valve Coil

With two decades as a leading expert in refrigeration compressors and their critical components, ascompressors.com understands that the performance of your cooling system hinges on precise control. In modern, high-efficiency refrigeration and air conditioning systems, Electronic Expansion Valves (EEVs) play a pivotal role. The heart of an EEV's precise operation lies within its expansion valve coil, which acts as the electro-mechanical actuator that precisely meters refrigerant flow. We proudly supply a comprehensive range of high-quality expansion valve coils to ensure your EEVs function flawlessly, delivering optimal system efficiency and stability.

An expansion valve coil, often referred to as an EEV coil or stepper motor coil, is the component that converts electrical signals from a system controller into mechanical motion. This motion precisely adjusts the valve's opening, allowing for dynamic and accurate control of refrigerant flow into the evaporator. This level of precision is crucial for maintaining optimal superheat, preventing liquid slugging, protecting the compressor, and maximizing the overall energy efficiency of the refrigeration system, especially under varying load conditions.

Core Expansion Valve Coil Types & Key Products We Offer:

Our carefully selected inventory includes expansion valve coils compatible with leading EEV brands and system designs. We focus on durability, precise electrical specifications, and robust construction to withstand demanding refrigeration environments:

• Standard Stepper Motor Coils: These are the most common type, converting electrical pulses into discrete mechanical steps to adjust the valve's position. We offer coils with various step resolutions and torque ratings to match specific EEV models and required flow control granularity.

• Linear Actuator Coils: Some EEV designs use linear actuators, where the coil directly drives a linear motion to open or close the valve.

• Pulse Width Modulation (PWM) Coils: While less common than stepper motors for EEVs, some designs may utilize PWM signals for continuous modulation, and we can source compatible coils.

Our product range includes coils designed for various voltage inputs (e.g., 12V DC, 24V DC, 230V AC) and connector types, ensuring compatibility with a wide array of EEV controllers and applications. We also supply coil mounting kits, specialized connectors, and protective enclosures to facilitate easy replacement and ensure long-term reliability. Each coil is built to resist moisture, vibration, and extreme temperatures, factors common in refrigeration environments.
