    This assembly provides 2 functions, a) dual cross-pilot load holding between motor ports M1 and M2, and b) cross-port relief protection between ports M1 and M2.

    • Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
    • Turn adjustment clockwise to decrease setting of the counterbalance valve and release load.
    • Backpressure at port 2 of the counterbalance valve adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.
    • Counterbalance valve reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.
    • The assembly's cross-ported direct acting relief valves exhibit rapid response characteristics that minimize pressure overshoot and also provide low reseat leakage (less than 5 drops/min (0,3 cc/min) @ 85% of cracking pressure).
    • Hydraulic motors leak. Therefore a mechanical brake is recommended to positively lock any stopped live load.

    • 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.
