Ports Y and L (if required): 0 bar

Minimum pilot pressure for correct operation is 8 bar

(1) Coil can be supplied also with 60 Hz of voltage frequency: in this case the performances are reduced by 10÷15% and the power consumption is 55 VA (DPHI) and 58 VA (DPHE*)

(2) Average values based on tests performed at nominal hydraulic condition and ambient/coil temperature of 20°C.

SWITCHING TIMES (average values in m sec)

Notes:

1) For configuration 70 and 75, times of switching ON and switching OFF are the same: this value is equal to time of switch ON of configuration 63.

2) TEST CONDITIONS

- Nominal voltage supply DC (direct) and AC (alternating) with connector type SP-666. The use of other connectors can affect the switching time;

- 2 bar of counter pressure on port T;

- mineral oil: ISO VG 46 at 50°C

3) The response time is affected by elasticity of the hydraulic circuit, by variation of hydraulic characteristics and temperature.

10 PILOT PRESSURE GENERATOR (OPTION /R)

The device /R generates an additional pressure drop, in order to ensure the minimum pilot pressure, for correct operation of the valves with internal pilot

and fitted with spools type 0, 0/1, 4, 4/8, 5, 58, 09, 90, 94, 49. The device /R has to be fitted when the pressure drop in the valve, verified on flow versus

pressure diagrams, is lower than the minimum pilot pressure value.

To modify the pilot/drain configuration, proper plugs must only be interchanged. The plugs have to be sealed using loctite 270.
