Steering cylinder valve-gctid820420

I have a leak on the valve on my steering pump reservoir. Pic of it below. Anyone know where or maybe a link to get a replacement.

This is for the upper helm on the 5788 and it's not holding any pressure.

Thanks Rick

Interestingly I appear to have one in the engine room and this one up At the flybridge helm. The pilothouse wheel is fine and the lower unit holds pressure. This one up on the bridge is leaking from the valve.

What I am looking for is where I get the actual valve to replace on this upper unit and see if that fixes it. My upper helm steering is much harder to turn.

Guessing this is some kind of booster or secondary unit just for the upper helm.
