Pressure compensator cartridges - CP701-1

Pressure compensators are used in combination with other valves for pressure and flow control. The valve is normally closed by spring pressure, through flow from 1 to 2 is possible only when the control pressure at 1 is higher than the spring loading and the pilot pressure at 3. When the pressure at pilot 3 is removed, a flow from 1 to 2 is achieved provided the pressure at 1 is sufficiently high to overcome the spring force.
