Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9EK4/V - Bosch Rexroth R900970410

A size 32 valve only works cleanly if its pilot stage does not have to push against the plant return pressure. The 4WRZ32W8-520-7X/6EG24N9EK4/V picks up control oil internally and routes it away separately through Y, at 520 l/min nominal flow and up to 350 bar.

Benefits

• The spool carries symbol W8 and the nominal flow is 520 l/min.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• This version carries no pressure reducing valve in the pilot stage, operating pressure reaches 350 bar.
• Control is handled by external amplifier electronics, and the valve is powered with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-10-09-0-05, FKM seals for HL fluid, maximum flow 1600 l/min, weight 43.02 kg.

Applications

Applications are large forming presses, forging hammers and hydraulic test equipment with a collecting return. Internal pick-up saves one supply line while the separate drain secures the characteristic. The amplifier electronics are mounted outside the valve.
