Proportional Directional Valve 4WRZ25W6-220-7X/6EG24N9TK4/D3V - Bosch Rexroth R900966671

Axes that behave differently in each direction need a matching spool symbol. The 4WRZ25W6-220-7X/6EG24N9TK4/D3V carries symbol W6, meters 220 l/min of rated flow and takes its pilot oil externally with an internal return.

Benefits

• Rated flow of 220 l/min in size 25, with up to 870 l/min across the valve.
• External pilot oil supply and internal pilot oil return on the pilot-operated main stage.
• Spool symbol W6 with three switching positions across four ports.
• Integrated pressure reducing valve in the pilot circuit for a steady pilot pressure.
• 20.52 kg, FKM seals, operating pressure up to 350 bar, connection diagram ISO 4401-08-08-0-05.

Applications

The internal return saves one line in the manifold when the tank port stays unpressurised anyway. The valve is used in medium sized feed and lifting axes. The command value comes from an external amplifier card.

Manufacturer

The valve comes from Bosch Rexroth and carries material number R900966671 in product family 4WRZ(E). The complete characteristic curves and limits are given in datasheet Proportional directional valve, pilot-operated (RE 29115) and Hydraulic valves and hydro- (RE 07600-B).
