Directional Spool Valve 4WEH16E7X/6EG48N9EK4/B10 - Bosch Rexroth R901098897

Control oil leaves the body of this pilot-operated directional valve through separate port Y, while supply comes internally from port P. This keeps the size 16 4WEH16E7X/6EG48N9EK4/B10 independent of tank line pressure as it distributes up to 300 l/min following spool symbol E.

Benefits

• Separate control oil drain through port Y independent of tank line pressure.
• Internal control oil supply from port P saves one further line.
• Spool symbol E in three switching positions across four ports.
• Up to 300 l/min at an operating pressure of no more than 280 bar.
• Weight of 9.82 kg with solenoid actuation on 48 VDC.

Technical data

Application

In manifolds with many valve stations and long collector lines, tank pressure varies with the number of actuators discharging at any moment. A dedicated drain for control oil decouples the pilot stage from that and keeps switching times reproducible. Permissible pressures at port Y are stated in the data sheet and have to be respected when routing the line.

Manufacturer

Manufactured by Bosch Rexroth, product family H-4W.H.., material number R901098897. Limit values for the control oil drain, characteristic curves and installation dimensions are given in the data sheet Directional spool valves, pilot-operated (RE 24751), supplemented by Hydraulic valves and hydro- (RE 07600-B).
