Proportional Directional Valve 4WRDE16V150L-6X/MXYWG/24A5 - Bosch Rexroth R901555688

Separated pilot oil paths are common in older plants and can rarely be altered. The 4WRDE16V150L-6X/MXYWG/24A5 takes pilot oil from outside and discharges it through its own return line, at 150 l/min nominal flow in size 16.

Benefits

• External pilot oil supply and external pilot oil return preserve the existing pilot routing.
• 150 l/min nominal flow, 460 l/min maximum, operating pressure up to 350 bar.
• Symbol V with three switching positions and internal position feedback for a linear characteristic.
• Control with ±10 V DC, supply 24 V DC, 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals, HL hydraulic fluid, weight 10.5 kg.

Applications

Typical installations are machine tool power units in which pilot oil and working oil stay separate. The external return keeps the pilot circuit free from back pressure in the tank line. At 150 l/min the valve serves medium cylinder axes at moderate speed.

Manufacturer
