Directional Spool Valve 4WEH16Y7X/6EG125N9EK4/B10 - Bosch Rexroth R901343796

Where the tank channel carries noticeable back pressure, the pilot stage should get a drain of its own. The 4WEH16Y7X/6EG125N9EK4/B10 is built exactly that way, takes its pilot oil internally and switches 300 l/min at up to 280 bar.

Benefits

• External pilot oil return, independent of back pressure in the tank channel
• Internal pilot oil supply, no additional pressure line is needed
• 300 l/min flow in the ISO 4401-07-07-0-05 interface
• Spool symbol Y, 4 ports, 2 switching positions, 125 VDC
• 10 kg, NBR seals for HL hydraulic fluid

Technical data

Applications

Versions like this sit in systems with long return lines or with filters and coolers in the tank run. A separate pilot drain keeps switching times steady there. The valve meets UKCA under Low-Voltage Directive SI2016/1091.
