1. Check that the solenoid valve complies with such parameters as the selected supply voltage, medium pressure, differential pressure, etc. In particular, if an error occurs, it will burn the coil. The power supply voltage fluctuation range should be in line with the rated voltage: 10%-15% 10%-10%, DC coil components should normally not be opened 2, take over the pipe flushing, metal powder residue in the tube and seal material, rust clear. Pay attention to clean media, media mixed dirt, impurities prevent the normal work of the solenoid valve, filter or filter should be installed in the pipeline.
3 Solenoid valves with 3 solenoids should be straight and mounted vertically on a horizontal pipe. If space restrictions or conditions are required, they must be installed according to the needs of the cell when ordering. Doing so will cause the solenoid valve to malfunction.
4, before and after the solenoid valve and manual stop valve, bypass position should be easy to repair solenoid valve failure.
5,
Solenoid valve is generally aimed at, can not stand up to indicate the direction of medium flow, usually installed on the valve body according to → installation direction. However, it can be reversed in a vacuum line or under special conditions.
6. If the medium will start to water from the water hammer phenomenon, you should use a water hammer to act on the solenoid valve or take appropriate precautions.
7, try not to let the solenoid valve power state for a long time, so it is easy to reduce the coil life or even burn the coil, this is, normally open, normally closed solenoid valve can not be used interchangeably.
8, steam side solenoid valve should be equipped with a trap, where the takeover should be inclined.
Solenoid valve installation and maintenance
Solenoid valves are commonly used and require attention for installation and maintenance:
