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). Flow up to 5600 l/min at Δp = 6 bar. Pressure up to 350 bar. MODEL CODE FOR COVERS Seals material: omit for NBR (mineral oil & water glycol) PE = FPM D = direct operated valve * Optional different provision or setting of the calibrated plugs in the pilot channels, see section ‫ݝ‬ normally closed; normally open; with shuttle valve for pilot selection; with hydraulically operated pilot check valve; Series number For model code of poppet, see section ‫ݚ‬ HYDRAULIC SYMBOLS
