Stainless steel Electric Solenoid Valve Normally Closed Pneumatic for Water Oil Air gas 12V/24V/220V Solenoid valve is an automatic basic component that uses electromagnetic force to control the on and off of fluid (gas or liquid). Its functions are mainly reflected in the following aspects: 1. Fluid control: Solenoid valve can quickly open or close the fluid channel to achieve fluid on and off control. At the same time, multi-way solenoid valve can also switch the fluid flow direction and control the movement direction of the actuator. 2. Automated control: Solenoid valve is suitable for occasions that require frequent switching, such as automated production lines and irrigation systems. By cooperating with PLC (programmable logic controller), sensors and other equipment, solenoid valve can achieve automated control and improve production efficiency and product quality. 3. Flow and pressure regulation: By adjusting the opening or switching frequency of the solenoid valve, the fluid flow can be controlled, which is suitable for occasions that require precise flow regulation, such as chemical and food processing. At the same time, solenoid valves can also be used to control fluid pressure, such as maintaining pressure stability or achieving pressure graded control in hydraulic systems. 4. Safety protection: In an emergency, the solenoid valve can quickly cut off the fluid to prevent accidents. This function is particularly important in dangerous fluids or high-pressure systems, and can protect the safety of equipment and personnel. 5. Energy saving and environmental protection: Solenoid valves can accurately control fluids and reduce waste. For example, in heating and air conditioning systems, solenoid valves can adjust flow as needed to achieve energy-saving effects. At the same time, through precise control, solenoid valves can also reduce leakage and emissions, and reduce environmental pollution. 6. Remote operation and control: Solenoid valves can be remotely controlled by electrical signals and are suitable for dangerous or inaccessible environments, such as petrochemicals and sewage treatment. This remote control function improves the safety and convenience of operation. In summary, solenoid valves play an important role in industrial automation, fluid control and other fields, and are indispensable components in modern automation and fluid control systems. _x000D_
