Flow control cn e enhnced y use,,, type spools. ilot restrictor restrictor module vlve incorported with the solenoid pilot operted directionl vlve enles meter out control of oil from the pilot chmer during shifting of the min vlve spool. his reduces trnsient shock.

Mounting olts (JIS 7, Strength Clss.9) 弁 Vlve 形 Model 式六角穴付きボルト Hex Socket olts 本 Qty数 M DGV-7 M DGV-H8 M 8 Mounting olts must e ordered seprtely. ightening torque of mounting olts M: 9 to N m M: to N m M: 7 to 8 N m Notes on Opertion Mounting orienttion o ensure sure switching of no spring detented type vlves, mount vlves so spool xis is horizontl. here re no mounting ttitude restrictions for other spool/spring rrngements. Solenoid energiztion lwys ensure tht one side of solenoid is deenergized efore energizing the opposite side. For spring centered, pressure centered nd spring offset vlves, solenoid should e continuously energized during circuit switching. Deenergiztion of solenoid will cuse spool to return to prescried position y spring force. For no spring detented type vlves, min spool will e mintined in switched position s long s the pilot pressure is mintined. lso, to ensure sure circuit switching, solenoid should e energized for more thn. second. Long periods of solenoid energiztion Cre should e pid s long periods of solenoid energiztion t high pressure my cuse spool sticking nd switching mlfunction. Drin nd pilot. For internl drin type vlves, pilot pressure ( port pressure of internl pilot vlves) must e higher thn min. pilot pressure + tnk line ck pressure. herefore the pressure difference must e mintined even when surge pressures occur in the tnk line.

Supltes re supplied with hex socket olts for mounting vlve. See pge R- for dimensions. DGSMV-**-D- used is pressure centered type. Mx. working pressure is M. For higher pressures, vlve should e mounted on mnifold lock.. xternl drin type vlve is recommended when surge pressures my occur in tnk line. Drin line should lso e piped directly to tnk.. In cse of internl drin vlve with spring sets, C, nd D nd spool types,,, 8, 9, nd, internl pilot type vlve cnnot e used if to port pressure drop during solenoid deenergiztion flls elow minimum pilot pressure. Use externl pilot type vlve in this cse. Mnul opertion For mnul switching, push the mnul override pin of solenoid pilot operted directionl vlve while the minimum pilot pressure is mintined. e wre tht, in cse of internl drin vlve, ctution force increses with higher tnk line ck pressure. (See pge -9) Solenoid indictor lmp For vlves with indictor lmps, the lmps will light when current flows to the solenoid. - Directionl Control Vlves
