DESCRIPTIONS
The DDCY-Q series vacuum pressure solenoid valve is designed to be installed on a dedicated mechanical vacuum pump. It is placed at the inlet of the mechanical vacuum pump and synchronizes with the pump's operation to control its opening and closing.
Stainless Steel Flexible Bellow Hose for Vacuum Pumps 
When the pump stops working or there is a sudden power failure, the valve can automatically close using atmospheric pressure and a vacuum valve plate, maintaining the vacuum system. This prevents air from entering the pump chamber through the orifice valve, avoiding contamination of the vacuum pump oil by reverse flow.
