Product Name: DYC-Q Series Low Vacuum Electromagnetic Differential Pressure Inflating Valve
Category: Vacuum Inflating Valve
The DYC-Q Series Low Vacuum Electromagnetic Inflating Valve is a specialized vacuum valve designed for installation on the intake port of mechanical vacuum pumps. It uses atmospheric pressure to automatically close the valve core and seal the vacuum system when the pump stops, preventing oil backflow and protecting the system.
