Vacuum electromagnetic differential pressure valve


The vacuum electromagnetic differential pressure valve is a special valve installed on a mechanical vacuum pump. Installed in the air inlet of the mechanical vacuum pump and turned on and off in synchronization with the pump. When the pump stops working or the power supply is suddenly interrupted, the valve can rely on the differential pressure between the atmosphere and the vacuum to automatically close the valve plate, close the vacuum system, maintain its vacuum, and charge the atmosphere into the pump chamber through the orifice. In order to avoid the countercurrent flow of the pump oil to the vacuum system.

Suitable working media are air or non-corrosive gases.
