Directionl Vlve NG 04 WL4.04 Instlltion dimensions ISO 4401/ DIN 4340 4
Functionl Description he directionl control vlves WL 4/04 consists of housing (1), control spool (5) with two centering springs (4) nd cylindricl operting solenoids (, 3). he three-position directionl vlves re fitted with two solenoids nd two springs. wo-position directionl vlves hve either one solenoid nd one return spring or two solenoids nd detent ssemly. he operting solenoids re D.C. solenoids. For C supply the solenoids re provided with rectifier, which is integrted directly into the connector. he plug connectors (6, 7) cn e turned y 90. y loosening the fixing nut (8), the solenoids cn e turned ritrrily in the rnge of 360, or replced. his enles the operting coils to e replced without opening the pressure-tight spces. In the cse of solenoid mlfunction or power filure, the spool of the vlve cn e repositioned y mnul override (9), provided the pressure in -port does not exceed 5 r. he sic surfce tretment of the vlve housing (1) is phosphte coted nd the operting solenoids (, 3) re zinc coted. echnicl Dt Nominl size 4 Mximum flow see p-q chrcteristics Mx. operting pressure t ports,, 30 r Mx. operting pressure t ports 10 r ressure losses see Δp-Q chrcteristics Hydrulic fluid Hydrulic oils of DIN 51 54/5 Other hydrulic fluids on request Fluid temperture rnge(nr) --30... +80 C mient temperture rnge... +50 C Viscosity rnge 0... 400 mm /s Mximum degree of fluid contmintion Clss 18/15 to ISO 4406. herefore we recommend filter with retention rte β 10 75 ermissile rted voltge vrition DC: ± 10 % C: ± 10 % Mx. switching frequency 15000 1/h Switching time, on; t U n nd viscosity 3 mm /s Switching time, off; t viscosity 3 mm /s DC: 30... 50 ms C: 30... 50ms DC: 70... 100 ms C: 30... 50ms Duty cycle 100 % Service cycle 10 7 Enclosure type to DIN 40 050 I 65 Weight-vlve with 1 Solenoid 0.9 kg Solenoid 1.5 kg Mounting position optionl KRCH GmH Gewerestr. 0 58791 Werdohl, Germny fon +49(0)3 9/935-0 fx +49(0)3 9/935 09 we www.krcht.eu mil info@krcht.eu
