DYC-Q Series Low Vacuum Electromagnetic Differential Pressure Inflation Valve is a new type of vacuum valve installed on the inlet of mechanical vacuum pump. The working principle is that the power supply of the mechanical pump is connected with the power supply of the solenoid valve coil in the same circuit. When the mechanical vacuum pump suddenly stops power and stops operation due to its working needs, the valve uses atmospheric pressure to make the valve core automatically close, cut off the passage connected with the vacuum system, and amplify the air into the pump to prevent the mechanical pump oil from returning to the vacuum. The system plays a role in protecting the vacuum system and is conducive to the restart of the mechanical pump.

The DYC-Q series low vacuum electromagnetic differential pressure charging valve is suitable for working air and non corrosive gases.
