I personally would not do that but just order new valves and have your existing ones serviced as backup spares. I have had just as many hassles with electric valves.
I will take the UP valves if you are going to throw them out!
EDIT: I have reason to believe turbine oil does a number on these valve orings. Get MAP to send you some spare Orings and some DOW lube and try to fix yourself is a viable option as well
