Proportional Directional Valve 4WRKE35W6-1000L-3X/6EG24K31/A1D3M - Bosch Rexroth R901136533

A press cylinder must keep a clean velocity profile over the full stroke even when the load changes abruptly. The 4WRKE35W6-1000L-3X/6EG24K31/A1D3M delivers 1000 l/min nominal flow at 350 bar operating pressure, and the on-board electronics keep the spool on the command value through internal position feedback.

Benefits

• 1000 l/min nominal flow in size 35, with a peak capability of 3000 l/min.
• 350 bar operating pressure in the main circuit, connection diagram ISO 4401-10-09-0-05 for subplate mounting.
• Spool symbol W6 with a linear characteristic curve, three switching positions across four ports.
• External pilot oil supply and external pilot oil return keep the pilot stage independent of main circuit pressure.
• Command value ±10 V at 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.

Application

Typical duty covers hydraulic presses, forging lines and test rigs where a large cylinder runs under position or force control. Subplate mounting to ISO 4401-10-09-0-05 makes the valve the output stage on a control manifold. At 69.5 kg, plan lifting gear for installation.

Manufacturer
