Proportional Directional Valve 4WRZE16W8-125-7X/6EG24N9K31/A1M - Bosch Rexroth R901483105

Plants with central pilot oil conditioning need no second pressure stage inside the valve. The 4WRZE16W8-125-7X/6EG24N9K31/A1M therefore leaves out the pressure reducing valve, is fed externally through X and Y and turns a plus or minus 10 V command into 125 l/min nominal flow.

Benefits

• Version without a pressure reducing valve, matching plants whose control pressure is already regulated.
• External pilot oil supply and external return through X and Y.
• 125 l/min nominal flow in size 16 against a series maximum flow of 460 l/min.
• Spool symbol W8 with 3 switching positions plus concealed auxiliary actuation for commissioning.
• Plus or minus 10 V command, NBR seals, weight 12.56 kg, operating pressure up to 350 bar, UKCA conformity.

Technical data

Applications

The valve is built into valve blocks of larger plants where several axes hang on a shared pilot supply. 125 l/min nominal flow suits medium cylinders at moderate speed. Through electrical position feedback the spool follows the command.
