Modular cartridge valves type LID
Check function, ISO 7368 sizes from 16 to 80
LID are cartridge valves for check function composed by a 2-way cartridge housed in a recess of standard dimensions
and by a closing functional element ቢ
called “cover”.
The cartridge is composed by a poppet
ባ hydraulically piloted by means of internal connections in the cover (X, Z1, Z2, F,
Y) and sliding into a drilled sleeve ቤ.
The flow is inhibited or permitted according to a proper pilot control.
Normally closed and normally open versions are available; cracking pressure
value depends on poppet spring ብ.

These valves are available in standard
sizes 16 to 80 according to ISO 7368
(DIN 24342).

Pressure up to 350 bar.
