Pneumatic Valve - Efficient and Reliable Automatic Control Solution
Pneumatic valves, as the core control components in the field of industrial automation, have become a key solution for achieving precise control in industries such as chemical, food, pharmaceutical, water treatment, and power due to their high efficiency and reliability driven by compressed air. The following analysis is conducted from five dimensions: core principles, type classification, control methods, application scenarios, and selection points:
1、 Core principle: Mechanical conversion driven by compressed air
Pneumatic valves use compressed air as a power source to convert pneumatic energy into mechanical energy, driving the valve core to move and achieve fluid control. Its workflow can be divided into three steps:
1. Air source treatment: After compressed air is generated by the air compressor, it needs to be filtered to remove impurities, stabilized by a pressure reducing valve, and lubricated with an optional oil mist device to ensure stable operation of the actuator.
