Directional Spool Valve 4WEH16HD7X/OF6EG205N9S2K4 - Bosch Rexroth R901071445

Rectifying a 230 V alternating supply leaves roughly 205 V direct voltage at the solenoid coil. The 4WEH16HD7X/OF6EG205N9S2K4 is rated for that value, at flows up to 300 l/min in size 16.

Benefits

• Solenoid rated 205 V DC, matched to a rectified mains supply.
• 2 switching positions to spool symbol D, 4 ports.
• External pilot oil supply and external return keep the pilot circuit independent.
• Flow up to 300 l/min, operating pressure up to 280 bar.
• Mounting pattern ISO 4401-07-07-0-05, mass 10 kg.
• UKCA to Low-Voltage Directive SI2016/1091, NBR seals for HL hydraulic fluid.

Applications

The valve is used in presses, lifting gear and test rigs whose solenoid valves run off a rectified alternating supply. A separate pilot circuit keeps pilot pressure stable even when working pressure collapses. NBR seals are fitted for mineral oil of class HL.
