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 called “cover”.
The cartridge is composed by a poppet hydraulically piloted by means of internal connections in the cover (X, Z1, Z2, F, Y) and sliding into a drilled sleeve .
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 .
These valves are available in standard sizes 16 to 80 according to ISO 7368 (DIN 24342).
