    This assembly is a combination of the cushion lock circuit and flow dividers. It provides flow division to two actuators in both directions. It provides overrunning load control in both directions. It provides cross-port relief protection. It provides thermal relief protection. It supplies make-up oil. It flushes hot and dirty oil out of the actuators.

    • The counterbalance valves should be set at 1.3 times the maximum load induced pressure.
    • Operating characteristics cause the leg of the circuit with the greatest load to receive the higher percentage of flow in dividing mode. If a rigid mechanism is used to tie actuators together, the lead actuator may pull the lagging actuator and cause it to cavitate.
    • Below the minimum flow rating there is not enough flow for the valve to modulate. It is effectively a tee. If flow starts at zero and rises, there will be no dividing control until the flow reaches the minimum rating.

    • All SAE o-ring porting per ISO 11926. All NPTF porting per ANSI B1.20.1. All BSPP porting parallel thread.
    • For detailed information regarding the cartridges contained in this assembly, click on the models codes shown in the Included Components tab.
    • Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
