1. loading solenoid valve : It adopts a two-position three-position normally closed structure and controls the on-off of the pipeline from the oil and gas tank to the intake valve through PLC instructions. When powered on, allow compressed air to enter the intake valve pipeline and open the intake port. When power is cut off, cut off the air passage and expel the residual air in the cylinder, then close the air inlet
2. Vent solenoid valve :
Open the valve for two positions and two normal positions to ensure that the pressure in the oil and gas tank of the air compressor remains at around 0.2MPa when it is no-load. When the machine is shut down and unloaded, cut off the power and release the gas to the intake filter to prevent excessive pressure
extension effect ：
1.Precise control of air flow direction : The flow direction of compressed air is switched through the magnetic field of the electromagnetic coil to ensure a stable air supply.
2.Enhance the level of automation : Interact with PLC to achieve remote control, reduce manual operation errors, and improve efficiency.
3. Safety protection : Quickly cut off the gas source in abnormal situations such as over-temperature and overload to prevent equipment damage or personnel danger.
