Spool symbol R3 blocks all four ports in mid position and keeps a load in place if the signal fails. Together with 350 l/min nominal flow, 350 bar and a 4...20 mA current command this gives an axis that does not drift at standstill.

Description

A suspended load must not sink when the axis stops. The 4WRKE25R3-350L-3X/6EG24EK31/F1D3M uses spool symbol R3 for that, releases 350 l/min nominal flow in operation and works up to 350 bar. The external pilot oil return keeps the pilot circuit clear of back pressure from the return line.

Benefits

Spool symbol R3 with a defined mid position for axes carrying a suspended load
350 l/min nominal flow, maximum flow 870 l/min
Operating pressure up to 350 bar in size 25
4...20 mA current command on the on-board electronics
Internal pilot supply with external return, insensitive to tank back pressure

Applications

Intended for hoists, baling presses and vertical press axes where the load is held at standstill. Four ports and three switching positions serve the standard cylinder circuit. The ISO 4401-08-08-0-05 interface is common across the industry.

Manufacturer

Bosch Rexroth, material number R901337449. The type code 4WRKE25R3-350L-3X/6EG24EK31/F1D3M defines size, spool symbol, electronics and seal material without ambiguity.
