Proportional Directional Valve 4WRKE10E50L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R900777015

At 50 l/min nominal flow in size 10 the pilot stage decides the response. In the 4WRKE10E50L-3X/6EG24ETK31/F1D3M it is built as internal pilot oil supply and return, and the main spool works with symbol E.

Benefits

• Internal spool position feedback at 50 l/min nominal flow.
• Linear characteristic curve between the command value 4...20 mA and orifice area.
• Symbol E in size 10, four ports, three switching positions.
• Pilot oil supplied and returned internally in the pilot stage.
• Operating pressure to 315 bar, throughput to 170 l/min, hydraulic fluid HL.
• 8.35 kg weight, 24 VDC supply voltage, NBR seals.

Applications

It is fitted wherever a cylinder or hydraulic motor has to be moved and held steplessly, for example on stretching lines, clamping fixtures and testing machines. With 50 l/min nominal flow it covers mid-range duties, and the pilot stage carries the forces at the main spool.
