Proportional Directional Valve 4WRTE32E1-400L-4X/6EG24EK31/A1M - Bosch Rexroth R900781259

An NG32 directional valve with internal spool position feedback controls oil flow according to command value, not just switching position. The 4WRTE32E1-400L-4X/6EG24EK31/A1M delivers 400 l/min rated flow through spool symbol E1, at an operating pressure up to 350 bar, with internal pilot oil supply and external pilot oil return.

Advantages

• 400 l/min rated flow with spool symbol E1 and connection pattern ISO 4401-10-09-0-05.
• Internal pilot oil supply with external pilot oil return, keeping tank back pressure from affecting the pilot stage.
• On-board electronics with an analog command value of ±10 V at 24 VDC supply voltage.
• Operating pressure up to 350 bar at a maximum flow of 1600 l/min.
• 7-pin connector (6 + PE) to EN 175201-804, weight 37.22 kg.

Applications

The valve suits test rigs, material testing machines and positioning axes where fine feed control through the analog command value matters more than rapid traverse. In presses it often handles the approach stroke while a second valve provides rapid traverse. The specified hydraulic fluid is mineral oil HL, sealed with NBR.
