Relief valves questions

[RealJeep]

Are the relief valves with the push button on top the ones where you can't move the tractor by pushing it?
I have one leaking at that top button, does it need to be replaced?
Are the two different valves interchangeable?

If the buttons are down, that's released.
Both types allow you to move the tractor.
I would mix the 2 styles though.

Mark Cafone from Machtech Direct can fix you up.
