Directional Spool Valve 4WEH16C7X/6EG24N9S2K4 - Bosch Rexroth R900784120

Inside a manifold block for heavy drives, the directional valve decides how quickly a cylinder starts and comes to rest again. The pilot-operated 4WEH16C7X with symbol C switches up to 300 l/min for that job and works at operating pressures up to 280 bar.

Advantages

• Switching pattern to symbol C in two positions, matched to circuits that need a defined starting state.
• Flow up to 300 l/min in size 16 across four ports in the main circuit.
• Operating pressure up to 280 bar, main stage and pilot stage rated for the same value.
• Pilot stage with external oil supply and external return, independent of the pressure in the switched circuit.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• NBR seals for HL hydraulic fluid at 10.39 kg weight and connection diagram ISO 4401-07-07-0-05.

Application

Typical installations are manifold blocks in presses, machine tools and power units with large cylinders. Size 16 with 300 l/min covers drives for which size 10 valves are rated too small. Because pilot oil is supplied and returned externally, switching behaviour is retained even when the main circuit carries no pressure.
