Installation and maintenance
The SDM102 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 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.

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

Installation and maintenance
Chamfer
Positioner kit
Body
Spool Normally the spools are interchangeable. Verify the smoothness during the assembly
NOTE -- All articulated parts inside cap, lever box and mechanical joystick are lubricated with synthetic base grease grade NLGI2
MALFUNCTION External leakage control kit or opposite side. Excessive internal leakage on A and B ports. Dropping load during transition while raising
CAUSE Worn spool seal due to mechanical actuation or high back pressure. Increase clearance between spools and body due to high wear High leakage on the load check valve. Main pressure relief valve blocked open.
REMEDY Locate the leakage and replace the seal. Check back pressure level. Replace the directional control valve and check the oil contamination level. Remove the load check valve and clean the seat. Remove and clean or replace the main relief valve. Remove and clean or replace the port relief valve. Check the pump and circuit.
