Applications
A separate control oil circuit keeps pilot pressure steady even when working pressure varies during a cycle. That matters for controlled acceleration and braking of axes on presses and test rigs. As no pressure reducing valve is fitted, the pilot pressure from the plant has to lie within the permitted range.
