Proportional Directional Valve 4WRLE16W6-200PJ-4X/MXY/24A1 - Bosch Rexroth R901564491

The difference between an open loop and a closed loop valve shows up at low speeds. The 4WRLE16W6-200 senses main spool position internally and corrects deviations itself, so the set flow is held even when load pressure changes. Size 16 provides 200 l/min nominal, with a limit of 800 l/min at 350 bar.

Benefits

• Internal main spool position feedback holds flow at the command value despite changing load pressure.
• 200 l/min nominal flow, valve limit 800 l/min.
• Linear characteristic with a fine control range for slow starts and accurate positioning.
• Command value plus/minus 10 V, on-board electronics on the valve fed from 24 VDC.
• External pilot supply and external pilot return for systems with their own control circuit.
• CE conformity, 350 bar operating pressure, valve weight 11.58 kg.

Technical data

Applications

Valves like this run positioning axes, materials testing machines and roll adjustment drives where cylinder travel is controlled. The fine control range around centre keeps millimetre infeed moves manageable without giving up the large flow. The subplate must follow the ISO 4401-07-07-0-05 port pattern.
