Directional Spool Valve 4WEH16R7X/6EG24N9K4/B10 - Bosch Rexroth R901212708

Both pilot oil paths of this valve lie outside the working circuit. Switching therefore stays the same even when the working pressure collapses during the cycle, at a rated flow of 300 l/min.

Benefits

• External supply and external return, so pilot pressure and pilot return are decoupled from the working circuit.
• Three switching positions to symbol R across four ports.
• 300 l/min at up to 280 bar, weight 9.84 kg.
• Subplate mounting to ISO 4401-07-07-0-05, the valve sits on the subplate without an adapter.
• Solenoid for 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid, 9.84 kg in weight.

Applications

Plants with their own pilot pump feed several valves at once this way and keep switching times repeatable. Size 16 is used on presses, lifting gear and large clamping systems. Installation is on a subplate to ISO 4401-07-07-0-05.
