Detail
Series DDCY Electromagnetic Differential Pressure Valve is one of the necessary components in vacuum system, it is installed at the inlet of mechanic vacuum pump, When the pump is stopping work or power off, the vacuum pump use atmosphere to break the pump connection with the vacuum pipe, and inflate air automatically, avoid the reflux of pump oil polluting the pipeline system and benefit of restart.
