DYC-Q series


Low Vacuum Electromagnetic Pressure Differential Inflatable Valve

DYC-Q series low vacuum electromagnetic differential pressure charging valve is a special vacuum valve installed on the air inlet of mechanical vacuum pump. Its working principle is that the power supply of the mechanical pump and the power supply of the solenoid valve coil are connected to the same power supply. When the mechanical vacuum pump suddenly loses power and stops running due to work needs, the valve uses atmospheric pressure to automatically close the valve core and cut off the channel connected to the vacuum system. At the same time, air is released into the pump to prevent the mechanical pump oil from returning to the vacuum system, which plays a role in protecting the vacuum system and is conducive to the restart of the mechanical pump. The applicable working medium is air and non-corrosive gas.
