-20°C +80°C (/PE seals)
Operating pressure For versions with proximity switches (/FI/NC and Ports P,A,B: 350 bar;
/FI/NO versions) maximum counter pressure Port T 210 bar allowed on T port is 5 bar
Rated flow
See diagrams Q/Δp at section
Maximum flow
60 l/min for DHU; 80 l/min for DHO, see operating limits at section

Relative duty factor Supply voltage and frequency Supply voltage tolerance
H (180°C) Due to the occuring surface temperatures of the solenoid coils, the European standards
EN563 and EN982 must be taken into account

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 (standard for DHO models) - see section 12 .
L1, L2, L3 = device for switching time control, installed in the valve solenoid (only for DHU and DHO models).
For spools 4 and 4/8 only device L3 is available.
F* = with proximity switch for monitoring spool position: see tab. E110.
MV, MO = auxiliary hand lever positioned vertically (MV) or horizontally (MO). For available configuration and dimensions see table E138.

Type of electric/electronic connector DIN 43650, to be ordered separately
SP-666 = standard connector IP-65, suitable for direct connection to electric supply source.
SP-667 = as SP-666, but with built-in signal led.
SP-669 = with built-in rectifier bridge for supplying DC coils by alternate current (AC 110V and 230V - Imax 1A).
E-SD = electronic connector which eliminates electric disturbances when solenoid valves are de-energized.
3 Spools
- spools type 0/2, 1/2, 2/2 are only used for two position valves: single solenoid valves, type DH*-063*/2 and double solenoid valves type
DH*-070*/2 and DH*-075*/2.
- 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.
- spools type 1, 4 and 5 are also available as 1/1, 4/8 and 5/1. They are properly shaped to reduce water-hammer shocks during the swiching.
- spools type 1, 3, 8 and 1/2 are available as 1P, 3P, 8P and 1/2P to limit valve internal leakages.
- 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.
- Other types of spools can be supplied on request.

(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.
(2) Average values based on tests preformed 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. Inrush current values correspond to a power consumption of about 150 VA.
