Proportional Directional Valve 4WRZE25W6-220-7X/6EG24K31/F1V - Bosch Rexroth R900731843

The 4WRZE25W6-220-7X/6EG24K31/F1V combines an interference resistant 4 ... 20 mA current command value with the large size 25 body. Nominal flow is 220 l/min and up to 870 l/min is possible at peak. Pilot oil arrives through X and the return leaves through Y, so the pilot stage stays independent of the working circuit.

Benefits

• A 4 ... 20 mA current command value is interference resistant over long runs and makes a cable break visible.
• 220 l/min nominal flow with a maximum flow rate of 870 l/min.
• External pilot oil supply and external return separate the pilot stage from the working circuit.
• Spool symbol W6 with three switching positions and an operating pressure of up to 350 bar.
• FKM seals, a weight of 19.96 kg and connection diagram ISO 4401-08-08-0-05.

Application

The valve is used on large lifting and pressing cylinders whose controller sits far away in the cabinet. Mineral oil of class HL is intended. Conformity is declared as UKCA for electromagnetic compatibility and the plug is 7-pole to EN 175201-804.
