Directional Spool Valve 4WEH16W7X/6EG24N9EK4/B10 - Bosch Rexroth R901205115

The hole pattern to ISO 4401-07-07-0-05 decides which subplate the 4WEH16W7X/6EG24N9EK4/B10 fits, and 9.73 kg of valve weight has to be counted in for the manifold and the mounting bolts. Pilot oil is taken internally and drained externally through a line of its own. Size 16 passes up to 300 l/min at a maximum of 280 bar, spool symbol W switches three positions.

Benefits

• Mounting pattern ISO 4401-07-07-0-05, subplate mounting with 4 ports
• Weight 9.73 kg as the figure for manifold and fastening design
• Internal pilot oil supply, external pilot oil drain
• 300 l/min flow, maximum operating pressure 280 bar
• Spool symbol W with 3 switching positions in size 16
• 24 VDC solenoid actuation via 3-pole connector (2 + PE) to EN 175301-803, NBR seals, HL hydraulic fluid

Applications

The external pilot drain carries pilot oil to tank on a separate line and stays clear of back pressure in the return of the main circuit. That suits systems with filters or coolers in the return line. Supply stays internal, so port P has to hold pilot pressure at all times.

Manufacturer
