Servo Directional Valve 4WSE2ED10-5X/45B14-315K31EV-143 - Bosch Rexroth R901495429

Where a control axis runs on a power unit with its own pilot pump, the valve has to take pilot oil from outside and return it outside. That is exactly how version -143 of the 4WSE2ED10-5X/45B14-315K31EV is arranged, with 45 l/min nominal flow and 3 switching positions in size 10.

Benefits

• Nominal flow of 45 l/min in size 10 keeps the axis finely controllable instead of merely switchable.
• External pilot oil supply and external pilot oil return suit units with a separate control oil circuit.
• On-board electronics save the separate amplifier card in the cabinet.
• FKM seals tolerate higher oil temperatures than an NBR set.
• Supply 24 V DC through a 7-pole connector (6 + PE) according to EN 175201-804, weight 3.84 kg.
• Spool symbol V with 3 switching positions keeps the function of the existing circuit diagram.

Applications

Typical places are test rigs, simulation tables and positioning axes in machine tools. The separately routed pilot circuit keeps control stable even when working pressure swings hard. For hot oils the FKM sealing is the right choice.
