The 4WRTE16V125P-4X/6EG24K31/A5M valve is produced by Bosch Rexroth for the 4WRTE Directional Control Valves series and directs hydraulic flow in automated systems. It is manufactured in valve size 16 and fits subplates that follow the ISO 4401-07-07-0-05 porting pattern. A V-coded spool with a P flow characteristic establishes the metering curve, while ports p, a, and b tolerate pressures up to 350 bar. Pilot oil is supplied internally, and the return is routed externally through port Y. Command signals arrive via a ±10 V interface with an enable line labeled A5, and the electronics operate on a DC supply that can range from 18 V to the 24 V nominal value with an upper limit of 35 V.
An electrical connector built to DIN EN 175201-804 and identified as K31 links the valve to the control cabinet. The electronics draw a maximum current of 1.6 A and consume no more than 72 VA, fitting typical power budgets for servo-hydraulic axes. The housing carries an IP65 rating to block dust and water jets encountered on production machinery. Spool position monitoring is present under option M, providing feedback required for closed-loop motion or safety circuits.
