Product Description

4V220 Pilot Operated Pneumatic Solenoid Valves

The pneumatic system is taken as an example to illustrate the application of the solenoid valve in industrial control. The so-called pneumatic system is a gas-based control system. In pneumatic systems, the medium of this energy is usually air. In actual use, the volume of air in the atmosphere is usually compressed to increase its pressure. Compressed air works primarily by acting on the piston or blade.In pneumatic systems, the role of the solenoid valve is to adjust the various states of the compressed air in the control system according to the requirements of the control. The pneumatic system also needs the cooperation of other components, including the power components, actuators, switches, display devices and other auxiliary devices. device. The power components include various Compressors, and the actuators include various cylinders. These are all indispensable parts of a pneumatic system. The valve body is an important device for the control algorithm to be realized.

For example(Application):

The check valve allows compressed air to enter the gas tank from the Compressor. When the compressor is closed, the compressed air is prevented from flowing in the opposite direction. When the pressure in the gas storage tank exceeds the allowable limit, the compressed air can be discharged; the directional control valve passes. The two ports of the cylinder are alternately pressurized and exhausted to control the direction of motion; the speed regulating valve can easily realize the stepless speed regulation of the actuator.The solenoid valve can be applied not only to pneumatic systems, but also to the same or similar applications in hydraulic systems and water pressure systems, such as low-power, non-oil-filled small electromagnetic reversing valves. Seals do not need to be supplied with oil. The gas does not pollute the environment and can be used in food, medicine, electronics and other industries.

Now, solenoid valve technology combined with control technology, computer technology, and electronic technology has been able to perform a variety of complex controls. For example, the solenoid valve can be applied in the field of intelligent control and applied in wireless control technology. Because the solenoid valve can be controlled by electromagnetic, it can interface well with various electronic systems, which is one of the main reasons for its wide application.Solenoid valves have been widely used in various fields of production. With the improvement of electromagnetic control technology and manufacturing processes, solenoid valves can achieve more sophisticated control, and play a role in realizing different pneumatic systems and hydraulic systems.

Daily inspection problem

  1. Is the electromagnet case temperature too high?
  2. Whether the spool works normally when the electromagnet is operating.
  3. Whether the solenoid valve is leaking. The internal leakage of the solenoid valve can be checked by the cylinder stroke to the end. Check the valve outlet for leaks.
  4. Is the fastening bolt and pipe joint loose?
  5. Is the voltage normal and the wires damaged?
  6. Whether the seal is damaged, the spool has no sludge, dust
  7. Check if the exhaust port is wet by oil, or if the exhaust will leave oil mist on the white paper to determine if the lubrication is normal.
