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.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
- Please consider stack requirements when choosing a coil. Sun explosion proof coils are larger than other coils and may interfere with components above or below this manifold. A tap in manifold can be used to add additional clearance.
- 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.
