Proportional Directional Valve 4WRKE16R3-220L-3X/6EG24K31/A1D3M - Bosch Rexroth R901499810

Large forming axes draw so much oil during a load change that system pressure dips briefly. The 4WRKE16R3-220L-3X/6EG24K31/A1D3M therefore takes pilot oil externally and returns it externally, at 220 l/min nominal flow in size 16.

Benefits

• External pilot oil supply and external return, independent of working pressure.
• 220 l/min nominal flow at a throughput of up to 460 l/min.
• Symbol R3 with a linear characteristic, three switching positions across four ports.
• Command value ±10 V, electronics on the valve, 24 V DC supply.
• 350 bar maximum operating pressure in size 16, connection diagram ISO 4401-07-07-0-05.
• 11.3 kg, NBR seals, hydraulic fluid HL.

Applications

A match for drawing presses, forging plants and heavy test axes with high load dynamics. In such plants the separate pilot supply usually comes from a small auxiliary power unit. Command value and supply share the 7-pole connector to EN 175201-804.
