Proportional Directional Valve 4WRKE35E1000L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901135910

When pilot pressure comes from a dedicated pump while the pilot return can share the main channel, external pilot oil supply combined with internal pilot oil return is the right layout. The 4WRKE35E1000L-3X/6EG24TK31/A1D3M converts that into 1000 l/min nominal flow at 350 bar.

Benefits

• Spool symbol E with a linear characteristic curve, three switching positions across four ports.
• External pilot oil supply with internal pilot oil return saves a separate drain line to tank.
• 1000 l/min nominal flow and up to 3000 l/min maximum flow in size 35.
• 350 bar operating pressure with connection diagram ISO 4401-10-09-0-05.
• On-board electronics with a ±10 V command value at 24 VDC, 7-pole connector (6 + PE).

Application

This version suits power units in plastics machinery and rolling mills where a separate pilot supply already exists. The valve works as the output stage on a manifold for speed or position control of large cylinders. Installed weight is 69.4 kg.
