Pilot-Operated Hydraulic Valve 4WRLE25 A1 10V OBE txoj hauj lwm tawm tswv yim

Engineered rau hnyav-cov haujlwm ua haujlwm hauv kev lag luam, 4WRLE25 A1 yog lub siab- khiav tsav- hydraulic valve uas xa cov kua dej loj nrog cov lus pom tseeb OBE txoj haujlwm thiab 10V tswj. Nws yog tsim los rau lub zog xav tau cov tshuab hydraulic hauv kev lag luam xws li kev tsim kho, mining, thiab kev tsim khoom hnyav, qhov chaw siab siab, cov dej ntws loj, thiab kev ua haujlwm txhim khu kev qha tsis yog - sib tham.

Rated flow ranges ntawm 350 mus rau 400 l / min (Δp=5 bar / tswj ntug), nrog rau qhov siab tshaj plaws txaus peev ntawm 1250 l / min kom tau raws li qhov xav tau ntawm siab - ntim hydraulic circuits. Thaum siv cov khoom siv roj av sab nraud, nws txhawb kev ua haujlwm siab tshaj plaws ntawm 350 bar rau cov chaw nres nkoj A, B, thiab P, thaum cov khoom siv sab hauv tso cai rau 280 bar. Chaw nres nkoj T tuav txog li 250 bar (pilot rov qab), ua rau nws haum rau hnyav hydraulic presses, loj khoom tuav, thiab mining machinery hydraulic systems.

A1 interface muab ± 10V hais kom nkag mus thiab ± 10V tus nqi tsim tawm, nrog rau qhov qis qis qis (<0.08%) and manufacturing tolerance ≤10% to ensure stable control in high-load conditions. The OBE integrates cable break detection and undervoltage protection (minimum supply voltage 19 VDC) to prevent system failures, critical for heavy-duty applications where downtime is costly. High response sensitivity (<0.05%) enables precise modulation of flow and pressure, even in dynamic operating scenarios like hydraulic excavator arms or large conveyor drives.

Weighing 19 kg, the valve features an ISO 4401-08-08-0-05 porting pattern for secure subplate mounting. It requires 6 ISO 4762 - M12 x 60 fixing screws (tightening torque 100 Nm ±10%) to withstand the mechanical stress of heavy-duty operation. An optional damping plate (D) reduces acceleration amplitudes on the OBE for frequencies >300 Hz, txhim khu kev ruaj khov nyob rau hauv siab - kev co ib puag ncig xws li kev tsim kho tshuab thiab cov mills.

Lub valve ua tau raws li EN ISO 13849-1 qeb 1 (PL c) rau kev hloov- tawm kev ua haujlwm, nrog rau kev xaiv IO-Txoj kev sib txuas (series Ntau dua lossis sib npaug rau 43) txhawb qeb 3 (PL d) rau kev nyab xeeb kaw -tawm hauv cov ntawv thov tseem ceeb. Nws nta lub caij nplooj ntoos hlav- lub hauv paus tseem ceeb ntawm lub valve ua haujlwm thiab tsis muaj kev nyab xeeb tsav spool positioning los tiv thaiv kev txav mus los, tiv thaiv cov neeg ua haujlwm thiab cov khoom siv. Ua raws li EMC cov lus qhia 2014/30/EU thiab RoHS cov lus qhia 2011/65/EU ua kom muaj kev sib raug zoo nrog cov qauv kev lag luam thoob ntiaj teb.

Tau tshaj cov roj ntxhia, cov kua dej biodegradable, thiab nplaim taws -cov kua dej tsis muaj zog, nws txhawb cov viscosity ntau ntawm 10–800 mm² / s (20–100 mm² / s pom zoo). Lub valve lub FKM los yog NBR cov ntsaws ruaj ruaj (xaiv raws li hom kua dej) tiv thaiv cov tshuaj degradation, thaum ISO 4406 18/16/13 cov kua dej huv huv tiv thaiv kev hnav rau cov khoom tseem ceeb. Nws ua haujlwm nyob rau hauv hydraulic kua dej kub ntawm -20 ~ +70 degree, haum rau cov khoom siv sab nraum zoov thiab cov chaw tsim khoom nrog qhov kub thiab txias hloov pauv.

Tsim los rau loj hydraulic presses, hnyav khoom tuav, machinery tsuas, thiab steel zeb hydraulic systems. Nws ua tau zoo nyob rau hauv daim ntawv thov uas yuav tsum tau muaj tus nqi siab thiab cov lus qhia meej txog txoj hauj lwm, xws li hydraulic forging presses, loj -scale conveyor drives, thiab cov cuab yeej siv hydraulic. Nws cov qauv tsim muaj zog thiab siab - siab kam rau ua kuj ua rau nws haum rau offshore hydraulic systems thiab hnyav industrial machinery ua hauj lwm nyob rau hauv hnyav hnyav.
