Directional Spool Valve 4WEH16D7X/6EG205N9S2K4 - Bosch Rexroth R900248852

A pilot circuit that takes neither pressure nor back pressure from the main line makes switching behaviour independent of the load. The pilot-operated directional spool valve 4WEH16D7X/6EG205N9S2K4 follows that principle and reverses up to 300 l/min in size 16 at 280 bar operating pressure.

Benefits

• External pilot oil supply and external pilot oil return, switching behaviour independent of load pressure.
• Spool symbol D, two switching positions on four ports.
• Flow up to 300 l/min, operating pressure up to 280 bar in size 16.
• Supply voltage 205 VDC, connector 3-pole (2 + PE) to EN 175301-803.
• NBR seals, connection diagram ISO 4401-07-07-0-05, weight 10 kg.

Application

The valve is used in presses, test rigs and power units with a central pilot circuit. Separate draining keeps the pilot section clear of residual pressure from filters or coolers. For the British market the UKCA declaration to the Low-Voltage Directive SI2016/1091 is available.
