The SDM080 valve is assembled and tested as per the technical specification of this catalogue.Before the final installation on your equipment, follow the below recommendations:-- the valve can be assembled in any position, in order to prevent body deformation and spool sticking mount the product on a flat

surface;-- in order to prevent the possibility of water entering the lever box and spool control kit, do not use high pressure wash down directly

on the valve;-- prior to painting, ensure plastic port plugs are tightly in place.

Carry--over configuration

NOTE -- These torque are recommended. Assembly tightening torque depends on many factors, including lubrication, coating andsurface finish. The manufacturer shall be consulted.

MALFUNCTION CAUSE REMEDY

External leakage pivot box lever orcontrol kit side.

Worn spool seal due to mechanicalactuation or high back pressure.

Locate the leakage and replace the seal.Check back pressure level.

Excessive internal leakage on A and Bports.

Increase clearance between spools andbody due to high wear

Replace the directional control valve andcheck the oil contamination level.

Dropping load during transition whileraising High leakage on the load check valve. Remove the load check valve and clean

the seat.

Inability to build pressure on A and Bports.

Pressure relief valve blocked open. Remove and clean or replace the valve.Inability to build pressure on A and Bports. Low pump pressure and flow. Check the pump and circuit.
