1 Directionl spool vlve types MM6 hnd lever operted MD6 rotry kno operted MR6 roller operted H6 hydruliclly operted NS6 31,5 M 80 dm 3/min K LICION Directionl spool vlves re intended for chnge in direction of fluid flow in hydrulic system nd thus it llows to chnge direction of movement of receiver - mostly piston rod of cylinder or hydrulic motor s well to use functions: on nd off. hese directionl spool vlves re used for suplte mounting in ny pos in hydrulic system. Directionl spool vlves cn e mde in differently operted design versions: hnd lever operted type MM6 rotry kno operted type MD6/MD6 roller operted type MR6/MU6 hydruliclly operted type H6 he directionl vlves re intended for suplte mounting in ny pos in hydrulic system. DESCRIION OF OERION Generl informtion Min ore nd nnulr ports,,, re mde in the housing (1) nd connected to its suplte connection. Directionl vlve is switched y shifting the spool (2) into one end pos. Vrious control functions result from the shpe of control spool (2) which ffects the chnge in configurtion of the connections etween ports,, nd in the housing (1). 4MM6 E -12/F... Directionl spool vlve - hnd lever operted type MM6 he spool (2) is shifted y chnging the pos of hnd lever (3) y mens of the pin (4). he spool return (2) to its rest pos is secured y centering springs (6) version MM6-12/. oss of the spool cn e fixed y mens of the detent (5) s well version MM6-12/F Directionl spool vlve my e equipped with the orifice (7) plced in port version MM6-12/ MM6 E -12/... ype MM6/ MD6/ MR6/ H6-1 - K

Spool return (2) to its rest pos is secured y the spring (6). Directionl spool vlve my e provided with orifice (7) plced in port version MR -12/ MR6 E-12/ Directionl spool vlve -hydruliclly operted type H6 he spool (2) is shifted y mens of the pressure supplied to connections of the cps (3) nd thus it llows to move spools (4). Spool return (2) nd its centering in neutrl pos (3-pos directionl vlves) or fixing end (2-pos directionl vlves) is secured y the springs (5) version H6-12/ ; hydruliclly (with oil pressure) version H6-12/O or y mens of detent version H6-12/OF OF. In versions: H6-12/O nd H6-12/OF OF the spool pos (4) is not fixed in cse of the lck of supply.
