Proportional Directional Valve 4WRKE25E1-350P-3X/6EG24K31/A1D3M - Bosch Rexroth R900717346

A size 25 valve rated at 350 l/min nominal flow belongs where an axis moves a lot of oil in a short time and still has to hit its position. Internal spool position feedback keeps the characteristic curve linear with a pronounced fine control range, and up to 870 l/min can pass through.

Benefits

• 350 l/min nominal flow at 350 bar operating pressure, peak 870 l/min over the ISO 4401-08-08-0-05 interface.
• Internal spool position feedback, giving a linear curve with a pronounced fine control range.
• External pilot oil supply and external pilot oil drain, matched to a centrally fed pilot circuit.
• ±10 V command value on on-board electronics, 24 V DC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• 17.9 kg installed weight, spool symbol E1, NBR seals for HL hydraulic fluid.

Applications

Used on presses, forging manipulators and large test cylinders. Pilot pressure there usually sits on a separate circuit shared by several valves. The fine control range allows slow approach movements despite the 350 l/min rating.
