Hi blokes,
i have come across this expansion valve (metering device) on an air to water chiller.
with out sounding stupid, can somebody explain how it works?
More so with the pipe connections on top of the device. I've never seen one like this before.
Obviously you have in the device & out the device, the bulb on the end of a capillary. But what are the other two connections for, what is there purpose?
The piece of pipe that comes out of the top of the device (NOT! the pig tail piece) this bends 90 degrees and enters back into the liquid line straight after the expansion valve??
Not your every day run of the mill TEV!
Thanks
