Expansion Valve Coil
Expansion Valve Coils
We supply premium expansion valve coils by Vickers, Bosch Rexroth, Danfoss, FUJIKOKI, Parker. These components ensure precise, energy-efficient, and ultra-quiet operation for industrial compressors with global technical support.
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 and Key Products:
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.
Essential Applications and Industries for Expansion Valve Coils:
The accurate and responsive control provided by high-quality expansion valve coils is indispensable across numerous critical cooling applications:
Commercial Refrigeration: Supermarket display cases, walk-in freezers, and industrial kitchens, where precise temperature control and energy efficiency are vital for product quality.
Industrial Refrigeration: Large-scale cold storage facilities, food processing plants, and blast freezers, demanding precise refrigerant metering for consistent performance under heavy loads.
HVACR Systems: Large commercial building HVAC, data center cooling, and VRF/VRV systems, where EEVs with reliable coils optimize comfort, energy consumption, and system responsiveness.
Specialized Cooling Equipment: Medical refrigeration, environmental chambers, and high-precision industrial chillers that require exact temperature regulation.
Heat Pumps: Maximizing efficiency in both heating and cooling modes by precisely controlling refrigerant flow.

Expansion Valve Coil Buyer's Guide
The Nameplate is Key: The model number alone is sometimes insufficient. We request a clear photo of the manufacturer’s metal nameplate. This confirms the specific Series, Voltage, and Bill of Material (BOM) number.
Refrigerant Verification: You must confirm the gas type (e.g., R134a, R404A, R290, or R410A). Using the wrong refrigerant in a Expansion Valve Coil compressor designed for a different gas will lead to immediate failure and void the warranty.
Voltage & Frequency Check: Global power grids vary. Whether you need 115V/60Hz (USA), 220V/50Hz (Europe/Asia), or 3-Phase 380V, this must be explicitly confirmed during the inquiry stage to prevent electrical burnout.
Application Matching: We verify if your application requires LBP (Low Back Pressure for freezers), MBP (Medium), or HBP (High Back Pressure for A/C and chillers). Installing an LBP compressor in an HBP application will cause the motor to overheat.
Performance Benchmarking: Before shipment, units undergo rigorous testing for volumetric efficiency, motor amperage draw, and noise levels
The Test Report: For peace of mind, we can provide a Quality Inspection Report or a video of the Expansion Valve Coil compressor under load test, proving it holds pressure and operates within factory specifications before it leaves our facility.
Spot Buy (Ready Stock): For urgent repairs, we leverage our global inventory of popular brands (Tecumseh, Copeland, Danfoss) to offer "2nd-Day Dispatch" on common Expansion Valve Coil models.
Batch Production (OEM Orders): For distributors or appliance manufacturers requiring 50+ units, we schedule a production run. This typically requires a 2-4 week lead time but offers significant cost savings.
Condition Clarity: We clearly distinguish between "Factory New" (fresh production) and "New Surplus" (older stock). We allow you to choose based on your budget and warranty requirements.
Robust Crating: We do not use standard cardboard for international freight. All compressors are bolted to a pallet and sealed in fumigated wooden crates compliant with ISPM 15 standards for global entry.
Upright Transport: Compressors must remain upright to prevent oil from entering the compression chamber (which causes "liquid slugging"). Our packaging includes "This Side Up" shock sensors and indicators.
Customs & Documentation: We handle the complex paperwork, including Commercial Invoices and Certificates of Origin, ensuring your goods clear customs smoothly whether shipping via DHL Air Express or Sea Freight to any port in the world.
