Hydraulic directional control valve of WEH series is an electro hydraulically directional operated valve is the union with 4WE6 directional hydraulic solenoid valveand large flow rate of hydraulic directional spool valve. The 4WE6 directional hydraulic solenoid valve uses for controlling the spool direction of the WH base. The advantage of electro hydraulically directional operated valve is much convenient operation control with high pressure and large flow rate.Finotek manufactures the WEH series is separated production and tested, first test the WE6 and WH separately, then the WEH unit should be tested again, it is eliminate the leakage between the WE and WH installation gap and the valve inner leakage must passed to guarantee its working reliability.FT-4WEH16 E–60/ 6EG24N Z5L (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(1) Producer code= FT(2) No code= 280bar H= 350bar(3) Size= 16(4) No code= Spool return by springs H= Spool return by hydraulic(5) Spool symbol= E,G,F, please see the spool symbol form(6) No code= With spring(7) Series no.= 60 for Size 16 O= Without spring OF= With detent, without spring(8) 6E= 4WE6 directional valve(9) DC voltage 24= G24V DC voltage 12= G12V AC voltage 220~230 50/60 Hz= W220V AC voltage 110 50/60 Hz= W110V(10) With manual override= N(11) No code= External pilot oil supply, external pilot of oil drain E= Internal pilot oil supply, external pilot oil drain ET= internal pilot oil supply, internal pilot oil drain T= External pilot oil supply, Internal pilot oil drain(12) No code= Without switching adjustment S= With meter-in control adjustment S2= With meter-out control adjustment(13) Plug-in connection with indicator lamp= Z5L(14) No code = Without Throttle insert B08= ThrottleØ0.8mm[0.031inch] B10= ThrottleØ1.0mm[0.039inch] B12= ThrottleØ1.2mm[0.047inch](15) No code= Without back pressure valve P4.5= With back pressure valve(cracking pre.4.5bar)(16) No code= Without pressure reducing valve D1= With pressure reducing valve(17) No code = NBR seals V = FKM seals(18) No code = Black Galvanization B= Blue Powder CoatingINTERNAL & EXTERNAL SUPPLY CONVERSIONExternal supply: Remove the valve cover, convert the pin smaller head towards to main valve.Internal supply: Rated the pin 180 degree, when the pin smaller head in opposite direction of external supply. INTERNAL & EXTERNAL DRAIN CONVERSIONExternal drain: Remove the nut (On "1" location) and screw in the M6 plugInternal: Screw out the M6 plug
