25+ Years of Specialized Expertise in Automotive Air Conditioning Components

If you’ve ever wondered how your car’s air conditioning system maintains that perfect temperature on a hot day, the answer lies in a crucial component: the AC control valve. At Qirun Auto, with over 25 years of specialized manufacturing experience, we’re experts in these essential components that keep drivers comfortable worldwide.

The Essential Role of AC Control Valves

The air conditioning control valve is responsible for regulating refrigerant flow throughout your vehicle’s AC system. Think of it as the “traffic controller” of your automotive air conditioning—it directs the right amount of refrigerant at the right time to maintain your desired cabin temperature.

Refrigerant Flow Regulation

The primary function of an AC control valve is to manage the flow of refrigerant between the high-pressure and low-pressure sides of the system. This precise regulation is what allows your AC to maintain consistent cooling performance.

Temperature Control

By adjusting the flow of refrigerant through the system, the control valve directly impacts the cooling output. When you adjust your temperature controls, you’re ultimately directing how the valve operates.

System Protection

AC control valves help maintain proper pressure levels throughout the system, preventing damage to components from pressure extremes that could lead to costly repairs.

How AC Control Valves Work

Most modern automotive AC systems use either thermal expansion valves (TXV) or orifice tubes to regulate refrigerant flow. While their designs differ, both serve the same essential purpose:

  1. Pressure Reduction: The valve reduces the pressure of liquid refrigerant coming from the condenser
  2. Temperature Adjustment: As pressure drops, the refrigerant cools significantly before entering the evaporator
  3. Flow Regulation: The valve meters the precise amount of refrigerant needed based on cooling demands
  4. Response to Load: It automatically adjusts flow rates based on temperature settings and ambient conditions

Why Quality Matters in AC Control Valves

As a manufacturer with over 25 years of industry experience, we at Qirun Auto understand that precision engineering is critical for AC control valves. A poorly manufactured valve can lead to:

Temperature Inconsistency

Improper refrigerant flow causes fluctuating cabin temperatures

Reduced Efficiency

Faulty valves make your AC work harder, decreasing fuel economy

Component Damage

Pressure irregularities can harm the compressor and other components

System Failure

Complete valve failure renders the AC system inoperative
