Installation and maintenance he SD5 valve is assembled and tested as per the technical specification of this catalogue. efore 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.

Excessive internal leakage on and ports. Dropping load during transition while raising 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. 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, verifing it s not dented.
