DDC-JQ electromagnetic vacuum gas charging valve isa vacuum globe type valve which can prevent the oil in the mechanical pump returning into the vacuum system. Usually installed at the pump air inlet, thus can be open or closed simultaneously with the pump.
a) Design a scientific control circuit, the coils temperature control can during a long time short than 50ºC;
b) With a reasonable valve plate sealing performance, thus also for harsh occasions with dust vacuum environment, such as moo crystal furnace vacuum system.
c) Low voltage start, low voltage maintained, applied for 50Hz / 60Hz power supply.
