Directional Spool Valve 4WEH16HD7X/OF6EG48N9K4 - Bosch Rexroth R900941135

Cycle time on a large cylinder depends on flow rate rather than pressure. This pilot-operated directional spool valve in size 16 passes up to 300 l/min, switches two positions to symbol D and is actuated by a solenoid at 48 VDC.

Benefits

• 300 l/min across the ISO 4401-07-07-0-05 interface in size 16
• 48 VDC supply voltage through a 3-pole (2 + PE) plug to EN 175301-803
• External pilot oil supply and external pilot oil return, so the pilot circuit works independently of the main pressure
• Two switching positions to symbol D across four ports
• 280 bar maximum operating pressure with NBR seals and HL hydraulic fluid
• 9.62 kg on subplate mounting in size 16

Applications

Typical duties are presses, lifting gear and clamping systems with large cylinder volumes where 300 l/min sets the cycle time. The 48 VDC version suits control systems built on that voltage level. External pilot oil supply keeps switching reliable at low working pressure.
