Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901048597

Plants with their own pilot pump need a valve that accepts control pressure from outside. This pilot-operated 4/3 proportional valve in size 32 uses an external pilot oil supply with internal pilot oil return, converting a ±10 V command value into 600 l/min of nominal flow at up to 350 bar operating pressure.

Benefits

• External pilot oil supply with internal return keeps pilot pressure decoupled from the main circuit
• Command value of ±10 V through a 7-pole connector (6 + PE) to EN 175201-804
• Nominal flow 600 l/min, maximum flow 1600 l/min, operating pressure to 350 bar
• Spool symbol W8, 3 switching positions plus a linear characteristic curve for smooth transitions
• Internal spool position feedback inside the on-board electronics, 24 VDC supply, mass 36.89 kg

Application

Sensible wherever a separate pilot pump supplies steady control pressure while main pressure fluctuates. The internal return saves the drain line on the manifold. Common installations include forging presses, rolling stands as well as large test cylinders.
