DYC-JQ series electromagnetic vacuum pressure differential inflation valveDetailed product description：

The DYC-JQ series electromagnetic vacuum pressure differential inflation valve is a specialized valve installed on mechanical vacuum pumps. Installed at the inlet of the mechanical vacuum pump and synchronously opened and closed with the pump. When the pump stops working or the power is suddenly interrupted, the valve can rely on the pressure difference between the atmosphere and vacuum to automatically close the valve plate, seal the vacuum system, maintain its vacuum degree, and fill the pump chamber with atmosphere through the throttle hole of the valve, thereby avoiding pump oil backflow and pollution of the vacuum system.
The applicable working medium is air or non corrosive gas.
