Proportional Directional Valve 4WRZ16E1-125-7X/6EG24ETK4/M - Bosch Rexroth R901403700

A cylinder is not meant to switch but to travel, that is to start, accelerate and decelerate. The 4WRZ16E1-125-7X/6EG24ETK4/M meters direction and flow in proportion to the command value, with a nominal flow of 125 l/min and up to 460 l/min at peak.

Benefits

• 125 l/min nominal flow with a maximum flow of 460 l/min.
• 350 bar operating pressure in size 16 to ISO 4401-07-07-0-05.
• Without pressure reducing valve in the pilot stage, pilot oil supply and return are routed internally.
• External electronics on 24 VDC, so amplifier and valve stay separately replaceable.
• 11.48 kg with NBR seals and spool symbol E1.

Applications

For feed, lift and press axes whose speed changes during the cycle. Because the electronics sit outside, the amplifier can be exchanged in the cabinet without removing the valve. Internal pilot supply requires a sufficiently high system pressure.
