Proportional Directional Valve 4WRZE25W8-220-7X/6EG24N9TK31/A1D3V - Bosch Rexroth R901239776

Spool symbol W8 sets this valve apart from the E versions of the same series. The 4WRZE25W8-220-7X/6EG24N9TK31/A1D3V meters 220 l/min nominal flow in size 25 with it, takes pilot oil externally and works up to 350 bar operating pressure.

Benefits

• Symbol W8 in 3 switching positions, 220 l/min nominal flow, 870 l/min maximum.
• External pilot oil supply with internal pilot oil return and a built-in pressure reducing valve.
• ±10 V command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Concealed manual override, operating pressure up to 350 bar.
• FKM seals, ISO 4401-08-08-0-05 interface, 20.76 kg, UKCA conformity.

Applications

The valve controls axes in presses, lifting gear and test rigs whose circuit diagram calls for symbol W8. On a replacement, check the pilot arrangement as well as the symbol, since external supply with internal drain is a combination of its own. A constant control pressure has to be present.
