Do You Know The Types And Characteristics Of Common Air Pressure Regulating Valves?

Air pressure regulating valve (Pressure Regulator) is a key component in pneumatic systems, mainly used to control and stabilize the air source pressure to ensure that the equipment can operate stably within the appropriate air pressure range. Different types of air pressure regulating valves are suitable for different working conditions and industry needs. This article will introduce several common air pressure regulating valves and their characteristics to help you better understand how to choose a suitable pressure regulating valve.

1. Direct-acting air pressure regulating valve

Features:

Simple structure, no additional control elements are required, and the air pressure is directly adjusted by the spring and diaphragm in the valve.

Sensitive response, suitable for small flow and low pressure regulation needs.

Small size, easy installation, suitable for laboratory equipment, small pneumatic tools, etc.

Application scenarios:

Pneumatic tools: such as pneumatic screwdrivers, paint spray guns, etc., need to stabilize the air source pressure and improve the operation accuracy.

Laboratory equipment: used for precision gas control, such as analytical instruments and medical equipment.

2. Pilot-operated air pressure regulating valve

Features:

Adopting pilot control mode, more accurate pressure regulation can be achieved through the combination of main valve and pilot valve.

Capable of handling larger air flow, suitable for medium and high pressure pneumatic systems.

Strong adaptability, can be used for automation equipment with high requirements for air pressure accuracy.

Application scenarios:

Industrial automation production line: control large cylinders, pneumatic clamps, etc. to ensure stable operation.

Semiconductor manufacturing: accurately control pressure in gas delivery system to ensure manufacturing accuracy.

3. Precision air pressure regulating valve

Features:

Adopting high-sensitivity diaphragm structure, it can accurately control small pressure changes.

Applicable to ultra-low pressure or high-precision pressure regulation occasions, such as 0.01MPa level fine-tuning requirements.

Fast response speed, can quickly adjust to the set pressure, and improve system stability.

Application scenarios:

Electronic manufacturing: used to control the airflow of precision equipment, such as chip packaging and laser cutting machines.

Medical equipment: such as ventilators and pneumatic delivery equipment to ensure stable air pressure supply.

4. Relief Regulator

Features:

It can automatically release excess air pressure when the system pressure exceeds the set value to prevent equipment damage.

It is suitable for environments with large pressure fluctuations to improve system safety.

It has a strong structure and can operate stably for a long time.

Application scenarios:

Gas storage equipment: such as gas tanks and gas distribution systems to prevent overpressure damage.

High-pressure pneumatic system: avoid sudden pressure fluctuations affecting equipment operation.

5. Electronic Proportional Regulator

Features:

It controls air pressure through electronic signals and can achieve remote adjustment, which is suitable for intelligent control systems.

It has high precision and real-time adjustment capabilities and can meet the automation needs of modern industry.

It can be connected with PLC and intelligent sensors to achieve digital control.

Application scenarios:

Intelligent manufacturing: such as robots and automated production lines to achieve precise air pressure control.

Precision spraying system: adjust air pressure to achieve high-quality spraying operations.
