Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24ETK31/A1D3M - Bosch Rexroth R900718023

Retrofits often lack the space for extra pilot oil lines. This variant of the NG32 proportional valve takes pilot pressure internally from the main circuit as well as returning it internally, so only the four main ports remain on the manifold. The ±10 V voltage command value meters 600 l/min of nominal flow.

Benefits

• Internal pilot oil supply plus internal pilot oil return call for no additional piping
• A ±10 V command value feeds on-board electronics with internal spool position feedback
• Nominal flow of 600 l/min with spool symbol W8, peaks reaching 1600 l/min
• Operating pressure to 350 bar, connection diagram ISO 4401-10-09-0-05, 4 ports
• Supply of 24 VDC through a 7-pole connector (6 + PE), NBR seals, mass 36.92 kg

Application

Fits manifolds where no pilot channel was ever provided, such as retrofits of older power units. In return the main circuit has to carry sufficient pilot pressure at all times. This version is common on injection moulding machines, presses as well as mid-size hydraulic axes.
