The secondary flangeable elements EDM-CB-__ can be interfaced and bolted on top of the A and B ports of the ED elements of the Directional Valve Assembly. They incorporate one or two cross piloted counterbalance valves which allow free flow toward the A and B outlet ports, and lock in a leak free mode the flow returning from the actuator. Pilot pressure in the opposite line reduces the pressure setting of the counterbalance valve in proportion to the pilot ratio until opening and allowing the flow return from the actuator.
•Hydraulic port sizes: A and B – SAE B
•Special coating and plating available, C.F.
