Product Name: DDC-JQ-B Series Electromagnetic Vacuum charging Valve
Category: Vacuum charging Valve
The DDC-JQ-B Series Electromagnetic Vacuum charging Valve is an essential component designed for installation on mechanical vacuum pumps. This valve is connected to the same power source as the pump, allowing synchronized control of the valve and pump operations. When the pump starts, the valve opens; when the pump stops or in the event of a power outage, the valve automatically closes, sealing the vacuum system. It also allows atmospheric air to enter the pump chamber through the intake port, preventing pump oil from flowing back and contaminating the vacuum system.
