Directional Spool Valve 4WEH16R7X/6EG24N9EK4/B10 - Bosch Rexroth R901211828

Four ports, three positions and a rated flow of 300 l/min describe how this valve works. Pilot oil comes from the working circuit while its return leaves the valve through an external line.

Benefits

• Three switching positions to symbol R with a defined centre position.
• 300 l/min rated flow at a maximum operating pressure of 280 bar.
• Internal pilot oil supply, external return, so the pilot stage needs no pressure source of its own.
• Hole pattern ISO 4401-07-07-0-05 for size 16, subplate mounting with no extra fittings.
• NBR seals and HL hydraulic fluid, solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, 9.88 kg.

Technical data

Applications

Presses, lifting gear and injection moulding machines use valves of this size for their large axes. The internal supply saves a line, while the external return keeps pilot pressure away from fluctuations in the tank line. At 9.88 kg the valve mounts straight onto the subplate.
