Proportional Directional Valve 4WRKE27W8-500P-3X/6EG24EK31/A5D3M - Bosch Rexroth R901569995

For fine metering at low flow, this 4WRKE27 pairs a characteristic curve with a fine control range and a symbol W8 spool. 500 l/min nominal flow at a maximum flow of 1000 l/min and an operating pressure up to 270 bar.

Advantages

• 500 l/min nominal flow at a maximum flow of 1000 l/min
• Fine control range in the characteristic curve for accurate metering at small signals
• Internal pilot oil supply, external pilot oil return
• Analog control with a ±10 V command value through the on-board electronics
• NBR seals for standard use with HL hydraulic fluid
• Size 27 to ISO 4401-08-08-0-05 at 15 kg

Applications

The valve suits applications that need fine metering at low flow and the ability to open up to 500 l/min on demand, for example on actuator axes with changing load conditions. The external pilot oil return relieves the tank port of the base unit. Operating pressure is limited to 270 bar for this configuration.
