Direct-Acting Hydraulic Proportional Valve 4WRPEH6 F1 4-20mA Tswj

Raws li ib qho ncaj qha -kev ua haujlwm proportional directional valve, nws integrates servo-zoo spool- lub tes tsho los ua ke thiab siab -rhiab heev inductive txoj hauj lwm tawm tswv yim, ua tiav cov micro- khiav txoj cai. Nruab nrog F1 interface, nws txhawb 4-20mA tam sim no lub voj tswj nrog kev tawm tswv yim ntawm 200 kΩ thiab qhov siab tshaj plaws load impedance ntawm 500 Ω, ua kom ruaj khov teeb liab kis tau tus mob nyob rau hauv me me -flow scenarios. Nrog hysteresis<0.1% and response sensitivity <0.05%, it maintains exceptional precision across rated flows of 4–40 l/min (Δp=35 bar/control edge), paired with linear "L" or inflected "P" characteristic curves (inflection points at 20%/40%/60%) to meet the demands of precision hydraulic systems.

Txais yuav tus tsav tsheb- roj- qauv tsim dawb, lub valve tshem tawm kev tsav tsheb siv roj thiab lub cev poob siab, txhim kho lub zog zoo rau cov tshuab hydraulic me me. Ua raws li ISO 4401-03-02-0-05 porting qauv, nws ua rau tus qauv subplate mounting nrog Ø8 mm cov chaw nres nkoj kom haum cov khoom siv hluav taws xob me me. Built-in OBE cov khoom siv hluav taws xob sib xyaw thiab 24VDC ntau lub zog hluav taws xob (19-36VDC) ua kom yooj yim txuas, thaum sib xyaw nrog cov roj ntxhia, HEES biodegradable roj, thiab HFC nplaim hluav taws roj (NBR / FKM foob kev xaiv) yoog rau qhov tseeb daim ntawv thov scenarios xws li cov cuab yeej kuaj thiab cov kab me me.

Featuring lub teeb yuag thiab compact vaj tse, lub valve yog qhov zoo tagnrho rau qhov chaw - txwv kev teeb tsa ib puag ncig thaum tswj kev ua haujlwm zoo. Kev khav theeb IP65 tiv thaiv kev ntsuas (nrog rau cov khoom sib txuas kom zoo), nws ua haujlwm ruaj khov hauv qhov kub thiab txias ntawm -20℃txog 50℃thiab txheeb ze av noo txog li 95% (tsis muaj condensation). Nws tiv taus qhov siab tshaj plaws ntawm kev ua haujlwm siab ntawm 350 bar, nrog rau kev ua haujlwm zoo heev rau kev vibration thiab kev poob siab, ua kom ntseeg tau kev ua haujlwm hauv cov chaw ua haujlwm tsis muaj paug.

Lub caij nplooj ntoos hlav-qhov nruab nrab tswj qhov nruab nrab cia li rov pib dua ua tsis tiav- txoj haujlwm nyab xeeb thaum lub zog tsis ua haujlwm lossis cable tawg (kuaj ntawm F1 interface tam sim no<2mA), preventing precision component damage. The factory-calibrated zero point (±1% adjustment range) allows on-site fine-tuning without disassembly. An optional electronics protection membrane (-967) prevents condensate formation in high-humidity environments, while detachable 6-pole + PE mating connectors simplify calibration and maintenance, reducing downtime for precision equipment.
