Change Over Valve

Function of change over valve

A changeover valve (also written as a changeover valve) is a common component in certain systems, such as turbocharged engines or HVAC (heating, ventilation, and air conditioning) systems. It is also called a diverter valve or a switching valve. Its primary function is to redirect or switch the flow of fluid or air between different paths or circuits.

In a turbocharged engine, the change-over valve is key to controlling the flow of compressed air. The diverter valve directs excess compressed air away from the engine's inlet when the throttle is closed to avoid damage caused by pressure build-up. This helps ensure engine longevity and optimal performance. In HVAC systems, change-over valves are used to control the flow of refrigerant in both cooling and heating modes. The device determines whether the system is in heating or cooling mode based on the temperature setting and the desired indoor environment.

In summary, a change-over valve acts as a switching mechanism to regulate the flow of liquid or gas, thereby ensuring the proper operation of different systems and equipment.

What is the principle of change over valve?

The working principle of the change-over valve is designed based on its structure and intrinsic structure, and it can change the fluid or air flow in various channels or circuits. The specific principles depend on the specific application and type of directional valve, but generally the following principles apply:

• Mechanical principle: Some switching valves are based on mechanical structures, such as springs, levers, or pistons. This type of valve controls fluid flow through movement and position.
• Solenoid principle: Some changeover valves use electromagnets to control the flow direction. When the solenoid coil is energized, a magnetic field is formed that drives the valve mechanism, thus controlling airflow.
• Pneumatic or hydraulic principle: In pneumatic or hydraulic systems, switching valves control the flow direction through differential pressure or fluid pressure.

The changeover valve principle depends on the design, application, and control mechanism. They use mechanical, solenoid, or fluid-based principles to alter fluid or gas flow to achieve the desired system function.
