1 Table H004/E ISO cartridge valves type LIDD and LIQV Flow control, ISO 78 sizes LIDD LIQV/K LIDD and LIQV are flow control valves not compensated, in ISO cartridge design, made by a functional cover and a way SC LI slipin cartridge. Covers are provided with regulating screw to adjust the cartridge opening. The cartridge is made by a spool (for LIQV) or poppet (for LIDD) sliding into a sleeve. The position of the spool or poppet and then the controlled flow, is manually set on the regulating screw of the cover; the cracking value depends on poppet spring. Size: to Max flow up to 500 l/min at p 5 bar Max : LIDD 40 bar LIQV 50 bar MODEL CODE FOR COVERS for model code of slipin cartridge/spool, see section, 5 Cover according to ISO 78 LI DD / * ** /* = NR T = HNR Flow control valve: DD =normally closed with stroke limiter QV =with manual setting Series number LIDD = 50 all sizes () LIQV = 0 all sizes Size for LIDD: = 4 = 40 = 5 5 = 50 = = Size for LIQV: = = 5 Options: see section 8 (): New series 50 of LIDD cover is highly recommended in combination with new high flow cartridges series 40 The use of standard flow cartridges (old series 0, and ) may cause the impossibility to fully close the poppet HYDRULIC SYMOLS ND CHRCTERISTICS LIDD LIQV H00
