1 Directionl spool vlve types MM hnd lever operted MD rotry kno operted MR roller operted H hydruliclly operted dm 3 NS up to35 M up to160 /min D SHEE - OER RION MNU NUL 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. Directionl spool vlves cn e mde in differently operted design versions: hnd lever operted type MM rotry kno operted type MD roller operted type MR hydruliclly operted type H he directionl vlves re intended for suplte mounting in ny position 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 position. 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). 4MM E - 62/... Directionl spool vlve- hnd lever operted type MM he spool (2) is shifted y chnging the position of hnd lever (3) y mens of the pin (4). he spool return (2) to its rest position is secured y centering springs (5) - version MM /. ositions of the spool cn e fixed y mens of the detent (6) s well - version MM /F.

Only fully functionl nd opertionl directionl vlve must e used. 2. During the period of opertion must e kept fluid viscosity cc. to requirements defined in this Dt Sheet - Opertion Mnul 3. In order to ensure filure free nd sfe opertion the following must e checked: proper of the directionl vlve clenliness of the hydrulic fluid 4. Due to heting of directionl vlve ody to high temperture erture,, the vlve shll e plced in such wy to eliminte the risk of ccidentl contct with the vlve ody during opertion or to pply suitle covers cc. to Europen stndrds N - EN ISO nd N - EN In order to provide tightness of the directionl vlve connection to the hydrulic system, one should keep the dimensions of the seling rings, tightening torques nd operting prmeters of the directionl vlve, specified in this Dt Sheet - Opertion Mnul. 6. person tht opertes the directionl vlve must e thoroughly fmilir with this Dt Sheet - Opertion Mnul. ype MM/MD/MR/H K
