1 able E0854/E Solenoid al valves DHI, DHE, DHER two stage, ISO 440 size 0, 6, 5 and 3 DHI, DHE and DHER are spool, two or three position, two stage al solenoid valves. hey are operated by a direct solenoid pilot valve available in three different executions: DHI suitable for C and DC supply with CURUS certified solenoids, see tech. table E00 DHE suitable for C and DC supply, high performances, see tech. table E05 DHER as DHE but with CURUS certified solenoids, see tech. table E05 Shellmoulding castings machined by transfer lines and then cleaned by thermal deburring. Optimized flow paths largely cored with extrawide channels to tank for low pressure drops. he valves can be supplied with optional devices, as adjustable chokes for control of switching times, see section for available options. Coils are easily replaceable without aid of tools. Surface mounting: ISO 440, size 0, 6, 5 and 3 Max flow up to 60, 300, 700, 000 l/min. ressure up to 350 bar DHE47**/H MODEL CODE I DH 7 / 4DC ** /* Seals material: omit for NR (mineral oil & water glycol) E = FM wo stage al control valve Solenoid pilot valve: I = DHI for C and DC supply with CURUS certified solenoids E = DHE for C and DC supply, high performances ER = DHER, as DHE but with CURUS certified solenoids Valve size: = 0 = 6 3 = 5 4 = 5 (high flow) 6 = 3 Series number Voltage code, see section = without connector See section for available connectors, to be ordered separately 00 = solenoid valve without coils (for DHI) 00C = C solenoid valve without coils (for DHE, DHER) 00DC = DC solenoid valve without coils (for DHE, DHER) Valve configuration, see section : 6 = single solenoid, center plus external position, spring centered 63 = single solenoid, external positions, spring offset 67 = single solenoid, center plus external position, spring offset 70 = double solenoid, external positions, without springs 7 = double solenoid, 3 positions, spring centered 75 = double solenoid, external positions, with detent Other configurations are available on request s Configurations / 6/ 70 67/ 7 s 0 67, see section CONFIGURIONS and SOOLS Configurations 6 Options, see section / / / 75 NOES (see also section 4, for special shaped spools): For D* are available only spools: 0, 0/,, /, 3, 4, 5, 58, 6, 7 For D*6 are available only spools: 0,,, 3, 4, 5, 58, 6, 7, 8, 9, 9 E085
