Directional Spool Valve 4WEH 10 H4X/6EG96N9K4 - Bosch Rexroth R978919351

A valve with spool symbol H holds a particular arrangement of the ports in its centre position that no other symbol reproduces. The 4WEH 10 H4X/6EG96N9K4 offers it in size 10 for a flow of 160 l/min.

Benefits

• Spool symbol H with 3 switching positions and 4 ports
• 160 l/min flow at a maximum operating pressure of 280 bar
• External pilot oil supply and external return, independent of the working circuit
• 96 VDC through a 3-pole (2 + PE) connector to EN 175301-803
• 6.8 kg in the ISO 4401-05-05-0-05 interface, NBR seals for HL

Applications

The valve is built into manifolds with a dedicated pilot circuit, for instance in power units that unload the main circuit. The centre position determines how the actuator behaves while the solenoids are off. The version is declared to UKCA under Low-Voltage Directive SI2016/1091.

Manufacturer

The Bosch Rexroth material number is R978919351. Circuit symbols for the whole range and the pilot pressure requirements are given in data sheet RE 24751, supplemented by RE 07600-B.
