I pulled the clutch valve off and the valve and spring that works with the clutch pedal seems fine but the one beside it not sure what it’s called. It’s real catchy and slides really hard.

Are you able to clean everything and free up the sticky valve ?

Polish the valve and clean the bore in the housing as best you can . The valve should slide smooth in the bore.

What was sticking up the valve ? rust, dirt or something else?
