Solenoid valve solenoid valve box selection and functions; (1) A two five-way solenoid valve is pilot-controlled single electric voltage normal use are two voltage DC24V, DC220V thread interface to be selected according to user requirements Hotels (due to pneumatic valve according to the site to determine the diameter size of the order). This characteristic of the solenoid valve is in the normal operating state by setting the pressure and set time the valve opens automatically closed after gas and waste water drain . The disadvantage is that in case of power failure has been closed. (2) Another two five-way solenoid valve is a pilot operated double solenoid normal use are the same. The disadvantage is that in case of power failure is always open. (3) Another 2-way solenoid valve is pilot-type single solenoid normal state is normally closed, the time needed to start to open. These three solenoid valve function according to user requirements, and the size of pneumatic valves on the line matching. What brand user can be, we can recommend the company. Solenoid valve box internal layout; the number of installations in general inside the solenoid valve according to user requirements, ranging up to a minimum 2-loop circuit 20 has the same specifications of the installation, there are mixed installation of different specifications, but also a single power double solenoid controlled mixing installation, more of the air box is installed inside the solenoid valve and so on. Solenoid valve control box can control each solenoid valve through the circuit breaker, it can also be controlled through the middle of each solenoid valve Continued appliances. If the power supply is 220v into the box-tank solenoid valve it is necessary to install a switching power supply 24v 220v turn 24v safe voltage. If power is converted into the box good safety voltage 24v is no need to use a switching power supply. Inside the solenoid valve is 220v is directly connected. Zero discharge, ground power lines rafts also be installed. Gas supply executives in the box or outside the box has a manual valve to control the entire gas path. Pressure solenoid valve may not exceed 0.8MPa. So solenoid valve box before normal operation must use filter regulator in order to adjust the pressure well after normal production.
