15 SDS5 Installation and maintenance he SDS5 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 working sections deformation and spools 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.
