Directional Spool Valve 4WEH16Q7X/6EG24N9ESK4/B10 - Bosch Rexroth R900968660

A pilot stage working against back pressure in the main return switches sluggishly. Pilot-operated directional spool valve 4WEH16Q7X/6EG24N9ESK4/B10 takes pilot oil internally and releases it through a port of its own, at 300 l/min in size 16.

Benefits

• Internal pilot oil supply, external pilot oil return for even switching times.
• Spool symbol Q, three switching positions across four ports.
• 300 l/min at a maximum of 280 bar operating pressure.
• 10.84 kg, NBR seals for HL hydraulic fluid.
• Interface ISO 4401-07-07-0-05, connector 3-pole (2 + PE), 24 V DC.

Technical data

Application

It belongs in power units with a return filter, an oil cooler or several actuators working in parallel. The separate pilot drain decouples switching time from how heavily the main return is loaded. Internal supply saves the pilot pressure line inside the block.
