Its from a JLG scissor lift. In the service manual they call it a control valve assembly.
I trying to find how they work but cant find much info online so I thought it may be known by other names.
Doesn't have to be this very one but I want to learn how they are inside and how the fluid flows.
It is a scissor lift, how to manually turn wheels to left? I don't want to make you read the reasons for doing this.
I think I have to relieve pressure to steer the wheels, what controls on the box must be turned for that...
