Proportional Directional Valve 4WRKE16W6-220L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901530520

A hoist should lift its load calmly and set it down without rocking. The 4WRKE16W6-220L-3X/6EG24EK31/A1D3M carries 220 l/min nominal flow with a linear characteristic curve, works up to 350 bar operating pressure and takes pilot oil internally while the drain leaves through a separate line.

Benefits

• Spool symbol W6 with a linear curve, flow follows the command value proportionally
• 220 l/min nominal flow and 460 l/min as the maximum flow
• Internal pilot supply, external pilot drain, independent of return pressure in the tank line
• 350 bar operating pressure in size 16, weight 11.22 kg
• On-board electronics, ±10 V command value, 24 VDC, NBR seals for HL

Applications

The valve is fitted in hoists, tilting devices and balancing axes that move heavy loads evenly. A linear curve makes ramp shaping in the controller easier. The ISO 4401-07-07-0-05 interface is the same across the whole of size 16.
