Series

number

LIDAS are 2-way ISO cartridge valves

with active pilot control, normally used

to shut-off the hydraulic line.

The particular poppet sealing grants

leak-free characteristics.

The poppet  is hydraulically

operated in both directions, ensuring in

this way higher reliability and faster

response time respect to the

conventional spring operated cartridge

valves.

The spring  ensures the valve

closing in absence of pressure in the

system.

They are available in different

executions:

LIDAS: without pilot solenoid valve

LIDASH: with on-off pilot solenoid

valve

Sizes:16 to 50 ISO 7368

Max flow up to 2000 l/min with Dp = 5 bar

Max pressure: up to 420 bar

ELECTRIC FEATURES - coils for pilot solenoid valves

(1) Coil can be supplied also with 60 Hz of voltage frequency: in this

c

ase the performances are reduced by 10÷15% and the power

consumption is 55 VA (-I) and 58 VA (-E, -EP)

(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

t

he holding current. Inrush current values correspond to a power

consumption of about 150 VA.
