I am having problems with an electronic retract valve and thinking of replacing it with a Jetronics valve. This is for air up, air down. The valve I have at the moment is spring loaded to one position so when the radio is turned off it is guaranteed to keep air pressure on the legs down, if it is plumbed in the correct way! I have a vague memory of reading that Jetronic valves don’t work like that and just dump the air when turned off, is that correct?
