Directional Spool Valve 4WEH16Y7X/6EG220N9K4 - Bosch Rexroth R901032864

Spool symbol Y together with fully external pilot routing forms a combination that a spare part case can rarely work around. The 4WEH16Y7X/6EG220N9K4 covers it and handles 300 l/min in size 16.

Benefits

• Spool symbol Y with 4 ports across 2 switching positions
• External pilot oil supply and external return, independent of working and tank pressure
• 300 l/min at a maximum of 280 bar, ISO 4401-07-07-0-05 interface
• 220 VDC through a 3-pole (2 + PE) connector to EN 175301-803
• 8 kg, NBR seals, HL hydraulic fluid

Applications

The valve is fitted into manifolds of presses and hoists that have their own pilot supply. Because symbol Y links the ports in a defined way while de-energised, it governs how the axis behaves at shutdown. UKCA under Low-Voltage Directive SI2016/1091 is declared.

Manufacturer
