Performace data
Following specifications are measured with:
• mineral oil of 46 mm2/s (46 cSt) viscosity at 40°C (104°F) temperature.
• standard spools, connecting P⇒A⇒B⇒T ports without flow multiplication
• 12 VDC and 24 VDC nominal voltage with tolerance ± 10%.

Following electrohydraulic controls need CED100X or CED400X electronic unit; for information contact Sales Department.

Installation and maintenance__________________________________________________________________________

The SDS140 valves are 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; order to prevent working section 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.

Electrohydraulic controls: hysteresis calculation rule

Hysteresis is calculated as difference between control currents (I2-I1), needed to reach 50% of nominal spool stroke, referred
to maximum control current IMAX, needed to reach 100% of spool stroke.
I2 is determined on spool stroke increase line, I1 is determined on spool stroke decrease line.
