ELECTRIC FEATURES - coils for pilot solenoid valves

(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 (-I) and 58 VA (-E)

(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. Inrush current values correspond to a power

consumption of about 150 VA.

(4) Only for pilot valve DHI

(5) Only for pilot valve DHEP

WARNING: the inobservance of following prescriptions invalidates the certification and may represent a risk for personnel injury

Safety valves must be installed and commissioned only by qualified personnel

Safety valves must not be disassembled

The inductive proximity FI or the inductive position switch FV can be adjusted only by the valve’s manufacturer or Atos authorized

service centers

Valve’s components cannot be interchanged

The valves must operate without switching shocks and spool vibrations
