    This is a reducer/reliever three-valve assembly. The open T-8A cavity will accommodate the reducer/reliever's pilot control cartridge. Sun offers a variety of pilot control options, including electro-proportional relief, and inverse electro-proportional relief. This assembly also includes an integral pressure compensated flow restrictor set at 0.10 gpm (0,4 L/min.).

    • This assembly includes a 3-port cavity plug allowing the relief flow from the pilot control valve to drain to T. This cavity plug can be changed to different plug or 3-port valve configurations providing circuit flexibility and convenience.

    • Why doesn't Sun anodize their aluminum bodies?
    • How big is a drop of hydraulic oil?  
    • Seal retainer plate is not required for this model.
    • 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.
