Installation and maintenance
The SDS150 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 s ticking mount the
product on a flat surface;
-- in order to prevent the possibility of waterentering the lever box and spool controlkit, donot usehigh pressurewash down directly
on the valve;
-- prior to painting, ensure plastic port plugs are tightly in place.
