Directional Spool Valve 4WEH16H7X/6EG24N9K4 - Bosch Rexroth R900933198

For a manifold with its own pilot circuit, the 4WEH16H7X/6EG24N9K4 controls the oil flow in three switching positions. The pilot-operated size 16 valve works with an external pilot oil supply and an external return, handles 300 l/min and weighs 9.74 kg.

Advantages

• External pilot oil supply and external pilot oil return, so the pilot pressure stays independent of the main circuit return.
• Spool symbol H in three switching positions, solenoid actuation with 24 VDC.
• Maximum flow of 300 l/min, maximum operating pressure of 280 bar.
• Connection diagram ISO 4401-07-07-0-05 with 4 ports in subplate mounting.
• NBR seals for hydraulic fluid HL, weight of 9.74 kg.
• A 3-pole connector (2 + PE) according to EN 175301-803 as the electrical connection.

Application

Typical applications are machine tools and plant engineering where several pilot-operated valves are fed from one common pilot pump. Size 16 covers actuators that call for up to 300 l/min. The separate return makes sense wherever the tank port of the main circuit carries back pressure.
