Table H050-5/E
On-off active safety cartridges type LIDAS, 2-way
ISO 7368 sizes from 16 to 50
ᕅ
LIDAS are 2-way active cartridge valves
designed for mounting in manifold blocks
and providing the leak-free shut-off function of the hydraulic line.
Configuration and construction:
The poppet ᕃ is hydraulically active
operated in both directions, ensuring in
this way higher reliability and faster
response time respect to the conventional
spring cartridge valves.
The spring ᕆ ensures the valve closing in
absence of pressure in the system.
They are available in different executions:
• without pilot solenoid valve
• with on-off pilot solenoid valve
assembled on the cartridge

Features:
• ISO 7368 sizes from 16 to 50
• typical applications: presses, injection
moulding machines
• max flow up to 2000 l/min with Δp = 5 bar
max pressure: 350 bar

Thanks to the areas ratio AAP/(AA+AB), see
section , ݘthe valve closing is always
ensured with a piloting pressure (X port)
equal to the line pressure (A or B line).
Only for LIDASH - Pilot solenoid valve:
I = DHI for AC and DC supply, with CURUS
certified solenoids
E = DHE for AC and DC supply, high performances
