Air Compressor Solenoid Valve Introduction and Product Recommendations
- Function and Role: The solenoid valve of the air compressor is a key control component in the air compressor. It is mainly used to control the opening and closing of the air circuit. For example, it controls the flow direction of the compressed air to achieve the reciprocating motion of the cylinder, adjusts the output pressure to realize the loading and unloading of the air compressor. It also has the function of system protection. When the pressure is too high, it automatically cuts off the air circuit, and quickly exhausts the air during emergency shutdown to ensure the safety of equipment and personnel.
- Structural Composition: It consists of a coil, a valve body, a valve core (armature), a spring and a seal. The coil generates magnetic force when energized to drive the valve core to move. The common voltages are AC 220V and DC 24V. The valve body is mostly made of brass or stainless steel, and the pressure - resistant range is 0.6 - 1.6 MPa. The valve core is directly controlled by the magnetic force to open and close the air circuit. The spring resets the valve core to close the air circuit after power - off. The seal is made of nitrile rubber or fluororubber to ensure airtightness.
- Selection Points: The diameter should be selected according to the air displacement of the air compressor, such as 1/4 inch, 3/8 inch, etc. The working pressure should be 20% higher than the maximum output pressure of the air compressor. In terms of medium temperature, the ordinary type is - 5℃ - 80℃, and the high - temperature type can reach 120℃. For the protection level, IP65 is selected for the dusty environment, and the explosion - proof occasion should meet the Ex d IIB T4 standard.
- ASCO 8210 series1: It is a brand of the United States ASCO. It is a normally closed two - position two - way valve. The valve body is made of brass/stainless steel, with an IP65 protection level, and manual emergency operation is supported (optional). The diameter range is DN6 - DN25, the pressure range is 0 - 10 bar, the medium temperature is - 20℃ to + 80℃ (fluororubber seal), the voltage is AC/DC 24V, 110V, 220V (optional), and the power consumption is 4 - 8W. It is suitable for scenarios such as air compressor control.
- Ingersoll Rand solenoid valve2: The material is brass, and the connection form is threaded. It is suitable for air medium. There are types such as loading type, unloading type, and integrated loading - unloading type. The fluid temperature is - 5 - 80 degrees, the working pressure is 0.0 - 1.6 Mpa, and there are various connection sizes. It can be used for screw air compressors and other equipment.
- Italian ODE 31IN1WOV23: It is a two - position three - way solenoid valve with a 1/8 caliber. It has a compact appearance and a maximum temperature resistance of 140 degrees. It can be used in air compressors.
