Modular cartridge valves type LIQV and LIDD Flow control, ISO 7368 sizes 16 ÷ 63 LIQV and LIDD are flow 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 spool (for LIQV) or poppet (for LIDD) ባ sliding into a drilled sleeve ቤ; the position of the spool or poppet, corresponding to the regulation of the valve, is manually set on the cover; cracking pressure value depends on poppet spring. These valves are available in standard sizes 16 to 63 according to ISO 7368 (DIN 24342). Flow up to 3500 l/min at Δp = 6 bar, pressure up to 350 bar.
