solenoid valve

1,Introduction WE10 solenoid directional valve, which uses solenoid to move spool directly, is a small directional valve, it mainly controls circulation and direction of fluid, it can also be used as pilot control valve to control all kinds of large valve (electro-hydraulic directional valve or 2-way cartridge valve), so that large power could be controlled. Solenoid and stackable valves to CETOP/ISO-03/05 standard is usually used as pilot valves. Screw-in cartridge are also used in the newly developed TLFA series. Various fuctions can be realized using cartridges and control covers,of which directional control is the most popular. 2,Features ·The standard style is that direct solenoid controls directional slide valve. ·Installation surface complies with DIN24340 A, ISO4401 and CETOP-RP121H ·Wet AC or DC solenoids with removable coil ·Solenoid can be rotated 90° ·Coils can be replaced without releasing any fluid ·Optional hand emergency ·Compact and high cost-effectiveness system design with superposition valve and multiple station bottom slab 3,technical data Installation position optional Ambient temperature,max (°C) 50 weight Weight with single solenoidvalve (kg) 4.7(=);3.9( ) Valve with 2 solenoids(kg) 6.3(=);4.7( ) Operating pressure Port A,B,P Mpa 31.5 Port T Mpa Up to 21(=);up to 16( )with symbols A and B,port T must be used as a drain port if the operating pressure is above the pemitted tank pressure Flow. max(L/min) Up to120 Flow for symbol v mm2 11(A/B→T);(P→A/B) Flow cross section (swithing position o) For symbol Wmm2 2.5(A/B→T) For symbol Q mm2 5.5(A/B→T) Petroleum, oil Mineral oil(HL,HLP)to DIN51524;Fast bio-degradable hydraulic fluid to VDMA24568,HETG,HEPG,HEES and the rest according to requirements Hydraulic fluid temperature range(°C) -30 to +80(with NBR seal) -20 to +80(with FPM seal) Viscosity range(mm2/s) 2.8--500 Degree of fluid contamination Maximum permissible degree to NAS1638 class 9.So the recommendatoryminimum filter is β10≥75 Type of voltage DC voltage AC voltage Voltage 12,24,42,60,96,110 180,205,220 42,110,120,220 50/60HZ Voltage tolerance(norminal voltage)(%) ±10 ±10 Power consumption w 35 - Holding current VA - 90 In-rush current VA - 550 Duty cyle concatenation concatenation Switching time to ISO 6403 (ms) Open 40to 60 15to 25 close 20 to 30 20 to 30 Swithing frenquency w/h Up to 15000 Up to 7200 Insulation to DIN40050 IP65 IP65 Coil temperature (°C) Up to +150 Up to +180 With electrical connections the earth(PE) must be correctly connected 4,Ordering code: 4 WE 10 D 50 / OF A G24 N Z4 V 1 2 3 4 5 6 7 8 9 1,working port 3=3 Service ports 4=4 service ports 2, size code(mm) 6=size 6 DG6 10=size10 DG10 3, spool type (see below picture) 4, series 50 to 59, unchanged installation and connection dimension 5, No code=with spring return O=without spring return OF=without spring return with detent 6, G24=DC24V W110R=AC110V,50HZ; W220 50=AC220, 50HZ 7, N=with fault inspection button 8, Z4= Square plug Z5=big square plug Z5L=big square plug with light 9 seal material Without code= butadiene-acrylonitrile rubber V= fluororubber
