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.

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.
