The main function of the pneumatic amplifier is to amplify the input pneumatic signal and output a larger pneumatic signal to drive the actuator. By increasing the flow and pressure of the output air stream, the pneumatic amplifier can significantly impro

The pneumatic amplifier amplifies the input pneumatic signal based on the pressure difference generated by the gas flow. When the input pneumatic signal enters the amplifier, it will cause the valve inside the amplifier to act, changing the air path on and off. Compressed air enters or exits different chambers of the amplifier depending on the size and direction of the input signal, resulting in different output pneumatic signals.
There are many types of pneumatic amplifiers, such as aerostatic amplifiers. Different types of amplifiers may differ in structure, working principle, and application. For example, the aerostatic amplifier uses the principle of aerostatic balance for amplification, which is suitable for occasions with large flow, high pressure, high precision and fast response.

• Aluminum alloy: Aluminum alloy is one of the main materials commonly used in pneumatic amplifiers. It is lightweight, strong, and has good corrosion resistance to meet the needs of most working environments. Pneumatic amplifiers made of aluminum alloy usually have a long service life and stable performance.
• Stainless steel: In some special environments, such as strong corrosive media or high temperature environment, stainless steel pneumatic amplifier is more suitable. Stainless steel has excellent corrosion and high temperature resistance to ensure the stability and reliability of amplifiers in these harsh environments.
