Proportional Directional Valve 4WRKE10W8-100L-3X/6EG24TK31/A1D3M - Bosch Rexroth R900708991

After every blow the system pressure dips briefly, yet the ejector still has to move calmly. The 4WRKE10W8-100L-3X/6EG24TK31/A1D3M therefore draws pilot pressure externally and keeps its 100 l/min nominal flow under control.

Benefits

• Pilot oil supplied externally, drained internally, pressure dips in the main channel leave pilot pressure untouched.
• 100 l/min nominal flow, up to 170 l/min, spool symbol W8.
• ±10 V command with internal position feedback and a linear characteristic curve.
• 315 bar maximum operating pressure in size 10, ISO 4401-05-05-0-05 pattern.
• 8.37 kg, NBR seals, supplied at 24 VDC through a 7-pole (6 + PE) plug.

Technical data

Applications

The valve works on ejectors and manipulators of forging presses, on hammers and on equipment with shock-type load changes. Port X is fed from a separate circuit, a Y line is not needed. Replacement valves must carry the same pilot variant.
