First, the use of solenoid valve box, centralized installation of solenoid valve, can reduce the power supply and control line of each solenoid valve, the centralized control system electrical control loop is connected to the solenoid valve box, the solenoid valve box only need to be laid to the pneumatic equipment, especially suitable for the start control system under poor working conditions.Second, using electromagnetic valve box, with bus communication function between master station and slave station can complete all communication with the communication thread control function, reduce a large number of cable and wiring work, save the cost of cable and artificial, and extension of the system is simply extend from the station, main control system without adding IO device, convenient operation and construction.Three, if the solenoid valve needs manual, automatic, interlocking and other control methods, the solenoid valve box must be used, with the corresponding control circuit to complete.Four, the traditional way to install solenoid valve on the equipment, the power supply, control line also needs to be connected to the equipment, if the environment is relatively bad or even explosion-proof requirements of the place, the requirements for solenoid valve will be very high (such as explosion-proof), then this way will have a great obstacle, and improve the cost of solenoid valve, explosion-proof solenoid valve price is at least 2-3 times compared with the ordinary solenoid valve,The solenoid valve box can be used in general solenoid valve, which can not only protect the solenoid valve, extend the life of solenoid valve and equipment, but also reduce loss and save costs.Five, solenoid valve box is a centralized control system, saving time in the equipment inspection, convenient maintenance, improve work efficiency, the traditional inspection method workload is relatively large, solenoid valve installation is scattered, maintenance takes a lot of time, the time can be shortened 3-4 times.Six, the use of electromagnetic valve box, for the follow-up maintenance work, it is very convenient to upgrade.
