Proportional Directional Valve 4WRKE16W6-220L-3X/6EG24ETK31/F1D3V - Bosch Rexroth R901527721

Where no separate pilot circuit exists, the valve has to take its pilot oil from the main channel itself. The 4WRKE16W6-220L-3X/6EG24ETK31/F1D3V does so internally, returns it internally, and controls 220 l/min nominal flow from a 4...20 mA command value.

Benefits

• 220 l/min nominal flow, up to 460 l/min flow at 350 bar.
• Internal pilot oil supply as well as internal pilot oil return, no extra pilot line in the manifold.
• 4...20 mA command value with internal spool position feedback and a linear curve.
• 16.2 kg weight, spool symbol W6 on the ISO 4401-07-07-0-05 pattern.
• FKM seals, HL fluid, 24 VDC through a 7-pole connector (6 + PE).

Technical data

Application

This layout suits compact control manifolds that carry only a pressure line as well as a tank line. The current signal stays unambiguous even when the control cabinet sits far away. With three switching positions and four ports the valve replaces identical units of the same pilot oil variant.
