Proportional Directional Valve 4WRDE27W6-500L-6X/MXY/24A5 - Bosch Rexroth R901538130

As soon as cylinder speed grows past the range of size 25, flow becomes the bottleneck. The 4WRDE27W6-500L provides 500 l/min nominal flow, up to 1000 l/min throughput and an operating pressure of 270 bar.

Benefits

• 500 l/min nominal flow in size 27, limit 1000 l/min.
• 270 bar operating pressure, connection diagram ISO 4401-08-08-0-05.
• Spool symbol W with linear curve, three switching positions, four ports.
• On-board electronics, ±10 V command value, 7-pole (6 + PE) connector to EN 175201-804.
• External pilot oil supply and external pilot oil return, 19.5 kg, NBR seals.

Application

Size 27 is used on forging presses, rolling mill adjustments and large hydraulic test benches. At 270 bar and 500 l/min the valve moves cylinders that swallow large oil volumes in a short time.
