Description

A rudder cylinder carries a load that changes with speed and sea state and still has to hold the commanded angle. The 4WRKE25W6-350L-3X/6EG24TK31/F1D3V meters 350 l/min rated flow at 350 bar maximum for that and measures the spool position inside the valve.

Benefits

Internal piston position feedback, linear characteristic, on-board electronics without an external amplifier.
350 l/min rated flow, flow up to 870 l/min, operating limit 350 bar.
Spool symbol W6 with blocked centre, three switching positions.
External pilot oil supply with internal pilot oil return, pilot operated spool in size 25.
Current command value 4...20 mA, 24 VDC supply, 18 kg, FKM seals, ISO 4401-08-08-0-05.

Application

Steering gear, stabilisers and heavy adjusting axes on board work with this control. The blocked centre holds the cylinder if the signal fails, which freezes the angle instead of losing it. For a voltage command signal the series carries the A1 code.

Manufacturer

Bosch Rexroth, material number R901398457.
