Is there a LOW PRESSURE VALVE on a 1994 940 with factory 134a? All the posts deal with older 240s having the LOW valve on the back of the compressor but I can't seem to find it anywhere on my 940s. There is one big valve with 134a marked on it and that's it. I found some info confirming that single valve theory but I am still not sure.

The low pressure valve is on a pipe attached to the accumulator-dryer (silver can).
