NOTES
1
Options A = Solenoid mounted at side of port B (only for single solenoid valves). In standard versions, solenoid is mounted at side of port A.
WP = prolonged manual override protected by rubber cap - see section 12 .
L, L1, L2, L3, LR, L7, L8 see section 10 = device for switching time control (only for DC solenoids).
L7 and L8 are available only for spool type 0/1, 1/1, 3/1, 4 and 5.
FI, FV = versions with proximity switch for spool position monitoring: see tab. EY010.
Y = external drain, only for DC version, to be selected if the pressure at T port is higher than the max allowed limits.
2
Accessories WPD/KE-DC = (only for DC supply) manual override with detent, to be ordered separately, see tab. K150
3
Special shaped spools
- spools type 0 and 3 are also available as 0/1 and 3/1 with restricted oil passages in central position, from user ports to tank.
- spool type 1 is also available as 1/1, properly shaped to reduce the water-hammer shocks during the switching.
- spool type 1/9 has closed center in rest position but it avoids the pressurization of A and B ports due to the internal leakages.

(1) In case of 60 Hz voltage frequency the performances are reduced by 20÷25% and the
power consumption is 90 VA (2) Average values based on tests performed at nominal
hydraulic condition and ambient/coil temperature of 20°C.
(3) When solenoid is energized, the inrush current is approx 3 times the holding current.
