Modular cartridge valves type LIM, LIR, LIC Pressure controls: relief, reducing, compensator, ISO 7368 size from 16 to 80 LIM, LIR and LIC are pressure control valves composed by a 2-way cartridge housed in a standard recess and by a functional “cover" ቢ. The cartridge is composed by a poppet ባ hydraulically piloted by means of internal connections in the cover (X, F, Y) and sliding into a drilled sleeve ቤ; cracking pressure value depends on poppet spring ብ. Pressure relief valve ቦ with manual setting is housed in the cover for sizes 16, 25 and 32 and is mounted on the cover for sizes 40…80. Poppets may have different geometrical shapes and area ratios as described in section ‫ ݛ‬to optimize the control. These valves are available in standard sizes 16 to 80 according to ISO 7368 (DIN 24342). LIMH*-3/***-E Flow up to 5400 l/min at Δp = 6 bar. Pressure up to 350 bar. MODEL CODE FOR COVERS F** Optional different provision or setting of the calibrated plugs in the pilot channels, see section ‫ݝ‬ Cover according to ISO 7368 MM = pressure relief control with manual setting; MHA= pressure relief control with solenoid valve for venting. Unloading when solenoid is deenergized; MHC= pressure relief control with solenoid valve for venting. Unloading when solenoid is energized; RA = pressure reducing control with manual setting. Open in resting position; C = pressure compensator to be coupled with flow control valves; CM = pressure compensator with mechanical max pressure regulation to be coupled with flow control valves.
