Explicit cost: The use of the solenoid valve box only increases the cost of the box and the communication module, and the other hardware costs are not increased in the traditional way. The role of the valve box and communication module is only about a few thousand yuan (according to the actual configuration). This is much lower than the cost of saving cable fees, bridge fees and engineering costs. According to the calculation of 150 pieces of 100 meters of cable, 1000 meters is 1500, and the cable bridge or cable trench is dozens of yuan per meter.

Invisible cost: The use of solenoid valve box will significantly reduce the maintenance workload, convenient for daily maintenance work and more convenient for future transformation and upgrading. The protective effect of the solenoid valve box on the solenoid valve prolongs the service life of the solenoid valve.
