Hey there

So this is something that I found interesting. This is a picture of a metering plug out of a Sporlan/Parker TXV on a Frick compressor LIOC circuit. I believe the package that this came off of is about 15 years old.

The reason for the r&r is foaming oil and poor oil temperature control. Disassembly showed reason for the misbehaving valve. Included is a picture of what the metering plugs looks like new.

When I first pulled the valve apart I thought that the erosion was so bad that the metering cone was completely gone, but the new part showed that it wasn’t that dramatic
