    4 WAY Valve?

    Hey everyone had a quick question about 4 way valves. Still new in the field learning as I'm going, and I've come across a problem with a 4 way valve in the field. I'm unsure on how to test to see if my valve is working properly, and was wondering if any of you had any ideas on how to troubleshoot problems like this?

    If it's stuck in the middle you'll hear it hissing and suction psi high, discharge low! If it don't shift at all! Well, that's pretty much a no brainer!!!

    Temp split in between common ports.

    3-5 suction and 5-10 discharge tops.

    3-5 Suction I remember in school them talking about when testing the 4 way valve, but the 5-10 discharge why is that gunna be a higher reading

    5-10 temp drop from discharge inlet to reversing valve to outlet of valve depending on which mode its in(far right or far left tube). Remember, if the valve is stuck your gonna be gaining heat into the suction stream and you will also have a temp drop across the discharge line through the reversing valve.
