DYC-Q series low vacuum electro-magnetic pressure difference valve is a necessary element in the vacuum system. It has been installed in the gas inlet of the oil seal mechanical pump. When the pump suddenly is blackout or stops running out of working requirements, the pump automatically drops the valve core by the utilization of atmospheric pressure. It cuts off the passageway which is connected with the vacuum system. At the same time it releases gas to the pump in order to avoid the mechanical pump oil return to vacuum system. In this way, it protects the vacuum system and is beneficial for the re-starting of mechanical pump.
