Directional Spool Valve 4WEH16E7X/6EG24N9TK4 - Bosch Rexroth R900923990

The 4WEH16E7X/6EG24N9TK4 controls the oil flow direction with spool symbol E in three switching positions and returns the pilot oil internally to tank. At 300 l/min and a maximum operating pressure of 280 bar, size 16 covers actuators with a high oil demand, the valve weighs 9.78 kg.

Advantages

• Spool symbol E in three switching positions.
• Internal pilot oil return with external pilot oil supply, which saves a separate return line.
• Flow of up to 300 l/min, operating pressure of 280 bar at most.
• Solenoid actuation with 24 VDC, 3-pole connector (2 + PE) according to EN 175301-803.
• Connection diagram ISO 4401-07-07-0-05 with 4 ports.
• Weight of 9.78 kg, NBR seals for hydraulic fluid HL.

Application

These valves are used in the manifolds of presses, clamping devices and hydraulic power units in mechanical engineering. The internal return cuts the piping effort because the pilot oil drains through the tank port of the valve. The pilot oil supply itself has to be connected externally.
