DYC-Q series low vacuum electromagnetic pressure differential inflation valveDetailed product description：

·DYC-Q series low vacuum electromagnetic pressure differential inflation valve
The DYC-Q series low vacuum electromagnetic pressure differential inflation valve is a new type of vacuum valve installed on the inlet of mechanical vacuum pumps. 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 circuit. When the mechanical vacuum pump suddenly loses power or stops running due to work needs, the valve uses atmospheric pressure to automatically close the valve core, cut off the channel connected to the vacuum system, and at the same time release atmospheric air into the pump to prevent the mechanical pump oil from returning to the vacuum system, playing a role in protecting the vacuum system and facilitating the restart of the mechanical pump. The applicable working medium is air and non corrosive gases.
