Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9K4/V - Bosch Rexroth R900953094

Fast movement of large cylinders is about flow, uniform behaviour is about a separate pilot circuit. The 4WRZ32W8-520-7X/6EG24N9K4/V combines both with 520 l/min nominal flow, spool symbol W8, external supply through X and external drain through Y, at up to 350 bar.

Benefits

• Spool symbol W8 with 3 switching positions and 520 l/min nominal flow in size 32.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• No pressure reducing valve is fitted, the installation supplies the pilot pressure itself. Operating pressure up to 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 43.16 kg.

Applications

The valve is used in presses, shears and forging plants whose cylinders swallow large oil volumes in a short time. Through the external pilot circuit every valve in a manifold responds alike. Installation requires a subplate to ISO 4401-10-09-0-05.
