Proportional Directional Valve 4WRZ10W6-50-7X/6EG24N9TK4/M - Bosch Rexroth R900744288

4WRZ10W6-50-7X/6EG24N9TK4/M uses an external pilot pressure source and drains through the valve tank gallery. Symbol W6 defines the behaviour of the main spool, nominal flow is 50 l/min and maximum flow 170 l/min.

Advantages

• External pilot oil supply from a dedicated pilot pressure source
• Internal pilot oil return, so only one extra line is needed
• 50 l/min nominal flow, maximum flow 170 l/min
• Symbol W6 with three switching positions, size 10
• Maximum operating pressure 315 bar, NBR seals, 7.76 kg mass
• Concealed auxiliary actuation, driven by external electronics

Application

Pilot-operated proportional directional valve in size 10 to connection diagram ISO 4401-05-05-0-05. Control is handled by external amplifier electronics at 24 VDC and the power connector is a 7-pole (6 + PE) type to EN 175201-804. Often the pilot pressure source is already available as an accumulator or auxiliary pump circuit, in which case a branch line to the valve is enough.
