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.

Application and selection of pneumatic actuators in the new energy industry

1、 Core application scenarios in the new energy industry hydrogen energy industry chain Storage and transportation process: Pneumatic actuators are used to control high-pressure hydrogen valves, which must meet the requirements of -253 ℃ ultra-low temperature environment and zero leakage. For example, the AT series actuators from Zhejiang Huaershi achieve rapid cut-off (response time<1 second) in hydrogen energy storage and transportation, ensuring safety. Refueling station: The high-pressure hydrogen refueling valve is driven by a double acting actuator and requires SIL3 functional safety certification

Hygienic valves: the key guarantee of the pharmaceutical and food industry

In the pharmaceutical and food industries, sanitary valves are the core equipment to ensure product safety and compliant production. Its design needs to meet strict hygiene standards (such as GMP, FDA, EC1935/2004). Through multi-dimensional guarantees such as material selection, structural design, cleaning and maintenance, it can prevent microbial pollution, cross-contamination and chemical migration. It is a "safety gate" that runs through the whole process of raw material processing, production and processing, filling and packaging.
