Gate valve to send out repair

Second surprise of the day , nobody bother to send the faulty gate valve to repair!

Gate valve functions as a separate valve to isolate whether to suck the gas through vacuum pump or shut off .

So the mechanism is very simple, extend to shut the valve , or retract to let the vacuum pump to suck the foreline gases.

So we always need to standby this part in case anyone spare down then can swop in.

Stay tune for more machine stuff!
