Solenoid Directional Valves (DEO)

1. DEO are spool type, two or three position directional control solenoid valves designed to operate in hydraulic systems.
2. Five cavities types valve body design, and may bear the high pressure and back pressure.
***** care has been taken in the design and the production of the ducts and the improvement of the spools has allowed relatively high
Flow rates to be accommodated with minimal pressure drops(??p).
4. They passed an endurance test with a mi- llion

The tests have been carried out with solenoids at a temperature of 40C and a voltage 10% less than rated voltage
With a fluid temperature of 40C. The fluid used was a mineral oil with a viscosity of 45mm / s at 40C. The values in
The diagram refers to tests carried out with the oil flow in two directions simultaneously T= 2bar( e. G...From P to A and
The same time B to T). In the case where valves 4/ 2 and 4/ 3 were used with the flow in one direction only, the limits
Of use could have va- riations which may even be negative. Rest times: The values are indicative and depend on
Following parameters: Hydraulic c- rcuit, fluid used and variations in hydraulic scales(pressure P, flow Q, temperatureT).
