Vacuum solenoid valve，Solenoid valve，Vacuum valve

Youdaoplaceholder0 Vacuum solenoid valve ‌ is a special valve installed on mechanical vacuum pumps, mainly used to control the opening and closing of vacuum systems. It controls the action of the valve by electromagnetic principle and is suitable for air and non-corrosive gas working medium ‌

Working principle

The vacuum solenoid valve controls its opening and closing state by using AC or DC power supply. It is equipped with a closed cavity inside, with a piston in the center of the cavity and electromagnets on both sides. When the electromagnet coil on one side is energized, the valve body is attracted to that side by controlling the movement of the valve body to open or close different exhaust holes, while the intake hole remains open all the time, allowing air to enter different exhaust pipes ‌

Application field

Industrial automation

In the field of industrial automation, vacuum solenoid valve is used for flow control, pressure control, temperature control and other links, realizing the automation control and optimization of production process ‌

For instance, in the pharmaceutical industry, vacuum solenoid valves are used in processes such as vacuum drying, concentration and transportation of drugs; In FOOD processing, for food vacuum packaging machine gas extraction and sealing operation ‌

Aerospace

In the aerospace field, vacuum solenoid valves play a significant role in aircraft hydraulic systems, rocket engine control systems, and spacecraft control systems. They can control the flow direction and pressure of hydraulic oil, as well as the control and regulation of rocket engine fuel and oxidant, ensuring the normal operation of the equipment

The high reliability, high precision and high efficiency of vacuum solenoid valves make them indispensable in the aerospace field.

Environmental protection and energy conservation

With the increasing demand for environmental protection and energy conservation, vacuum solenoid valves are also widely used in the fields of environmental protection and energy conservation. In the field of environmental protection, they are used for waste gas treatment and sewage treatment to reduce environmental pollution. In the field of energy conservation, applied in air conditioning and refrigeration equipment to improve energy efficiency ratio, reduce energy consumption ‌

Semiconductor manufacturing and photovoltaic industry

In SEMICONDUCTOR manufacturing, vacuum solenoid valves are used for vacuum extraction, gas delivery and separation in manufacturing processes to ensure high QUALITY production of SEMICONDUCTOR chips ‌

In the photovoltaic industry, they are applied to solar panel vacuum coating and cleaning processes to improve panel efficiency and quality ‌
