Proportional Directional Valve 4WRTE27W8-500L-4X/6EG24K31/A1V - Bosch Rexroth R901094203

Existing controllers usually issue their command value as a voltage. This version of the NG27 proportional valve stays with ±10 V, meters 500 l/min of nominal flow under closed-loop spool control plus works at a maximum operating pressure of 270 bar with flow reserve to 1000 l/min.

Benefits

• A ±10 V command value connects straight to existing analog outputs, no signal conversion needed
• Nominal flow 500 l/min, maximum flow 1000 l/min, operating pressure to 270 bar
• Spool symbol W8 with linear characteristic curve, 3 switching positions, 4 ports
• FKM seals for higher oil temperatures, HL hydraulic fluid
• On-board electronics on 24 VDC, 7-pole connector (6 + PE), mass 19.5 kg

Application

Meant for forming presses, test rigs plus feed axes whose controller already provides a voltage output. Changing to a current valve would call for extra converters, which this version avoids. Connection diagram ISO 4401-08-07-0-05 keeps it interchangeable with other NG27 valves.
