Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9TK4/D3M - Bosch Rexroth R900976869

The step response of a pilot-operated valve hangs on the pilot pressure. The 4WRZ10W8-50-7X/6EG24N9TK4/D3M draws it from an external source and works at 50 l/min nominal flow in size 10.

Benefits

• External pilot oil supply with internal return, stable pilot pressure with one line fewer.
• 50 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
• Spool symbol W8, 3 switching positions, 4 ports to ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot stage for a defined pilot pressure.
• 8.24 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications

The version is wanted on cycling machines such as injection moulding plant and forming presses. The middle nominal step keeps control quality in the feed range and still allows brisk travel. Through the external amplifier card, ramps can be matched to the cycle.
