Directional Spool Valve 4WEH16H7X/6EG24N9K4/B10 - Bosch Rexroth R900716161

Cold oil raises viscosity, and the pilot stage then depends on pilot pressure that is reliably present. The 4WEH16H7X/6EG24N9K4/B10 draws it from an external circuit, shifts to spool symbol H and carries up to 300 l/min at a maximum of 280 bar.

Benefits

• External pilot oil supply and external pilot oil return, pilot pressure is available independently of the main circuit.
• Spool symbol H in three switching positions, four ports in size 16.
• 300 l/min at a maximum operating pressure of 280 bar.
• 9,72 kg on subplate mounting to ISO 4401-07-07-0-05.
• 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803, NBR seals for HL hydraulic fluid.

Application

Machines with long idle periods and installations in unheated halls benefit from a separate pilot supply. The valve also stays ready to shift during unloaded circulation. The port pattern to ISO 4401-07-07-0-05 follows the size 16 standard.
