Directional Spool Valve 4WEH16D7X/6EG24N9EK4/11B08 - Bosch Rexroth R901161045

Switching 300 l/min reliably in size 16 calls for a pilot-operated directional valve. The 4WEH16D7X/6EG24N9EK4/11B08 carries exactly that flow across mounting pattern ISO 4401-07-07-0-05 and works with spool symbol D in two switching positions. Pilot oil is taken internally from the main circuit while the pilot oil return is routed externally. Weight is 9.68 kg.

Benefits

• 300 l/min flow in size 16
• 280 bar maximum operating pressure as the design ceiling of the circuit
• subplate mounting to ISO 4401-07-07-0-05 with 4 ports
• spool symbol D with 2 switching positions, pilot-operated spool
• 24 VDC solenoid actuation, 3-pole connector (2 + PE) to EN 175301-803
• NBR seals released for HL hydraulic fluid, weight 9.68 kg

Technical data

Applications

Pilot-operated valves of size 16 sit where large cylinders and hydraulic motors are moved, in presses, hoists and rolling mill drives. Internal pilot supply saves a separate feed line, the external drain keeps the pilot stage clear of back pressure in the tank gallery. Rate the system so that 280 bar is held even under pressure peaks at the moment of reversal.

Manufacturer

Bosch Rexroth lists the valve as material number R901161045 in product family H-4W.H.. . Two manufacturer documents are on file, performance limit curves and pilot oil demand are given in the data sheet.
