With two decades of dedicated expertise in the refrigeration industry, ascompressors.com understands that optimal system performance goes beyond just the compressor. The expansion valve is a critical, yet often underestimated, component that precisely controls the flow of refrigerant into the evaporator, ensuring maximum cooling efficiency and protecting your compressor from liquid slugging or overheating. As a trusted supplier of refrigeration compressors and their vital accessories, we offer a comprehensive range of high-quality expansion valves designed for precision, reliability, and longevity.

An expansion valve serves as the metering device in a refrigeration or air conditioning system. It reduces the pressure of the liquid refrigerant, allowing it to flash into a mixture of liquid and vapor before entering the evaporator. This controlled expansion is crucial for maintaining the correct evaporator superheat, which directly impacts the system's efficiency, capacity, and the overall lifespan of the compressor.

Core Expansion Valve Series and Key Products:

We stock a comprehensive range of expansion valves from leading manufacturers, ensuring you have access to the right component for any application. Our offerings include:

• Thermostatic Expansion Valves (TXV/TEV): These are the most common type, using a sensing bulb to react to the superheat of the refrigerant vapor leaving the evaporator. We provide TXVs with internal or external equalization, various connection types (flare, solder), and a wide range of tonnage capacities and charge types to match specific refrigerants (e.g., R-134a, R-404A, R-410A). Key components include the power element, diaphragm, and needle valve assembly.

• Electronic Expansion Valves (EEV): Representing advanced control technology, EEVs use stepper motors and electronic controllers to precisely modulate refrigerant flow. They offer superior superheat control, faster response times, and enhanced energy efficiency compared to TXVs, particularly in systems with varying loads. We supply the EEV body, stepper motor, and compatible control boards.

• Automatic Expansion Valves (AEV): Simpler in design, AEVs maintain a constant pressure in the evaporator. They are less common in modern large-scale systems but are still found in specific constant-load applications.

• Capillary Tubes: For smaller, fixed-load systems (like domestic refrigerators or small window AC units), capillary tubes act as a simple, non-adjustable expansion device, offering a cost-effective solution.

We ensure a diverse inventory, including valves with different MOP (Maximum Operating Pressure) settings, orifices, and body configurations to perfectly match your system's design requirements.

Critical Applications and Industries Benefiting from Our Expansion Valves:

Precise refrigerant control provided by our expansion valves is vital across a wide spectrum of cooling applications:
