-- pilot rexroth proportional valves NG10 to NG35 with approximately 20% positive overlap, see symbols e. / w. / R5 and characteristic curves -- rexroth proportional valve can be adjusted by the position control main stage with built-in electronic device (OBE) and inductive displacement sensor, which has been calibrated at the time of delivery -- rexroth proportional valve electronic compensation and overlap has been calibrated, please refer to the characteristic curve range ± 0.5v - linear valve, with anti-rotation device - flow characteristic • S = progressive -- pilot valve without position control, four-three-way function, optimized control edge, rexroth proportional valve for position controlled primary stage stability, in the middle of safety when closed location -- use electro-hydraulic controls for production systems with higher requirements -- for plate construction, pass NG10, ISO 4401-05-05-05-94, NG16 to ISO 4401-07-06-0-94, NG25 to ISO 4401 (high-traffic NG27) to ISO 4401-10-08-0-94 -08-07-0-94 and NG32 (high flow NG35)
