Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/F1V - Bosch Rexroth R900962041

Fewer interfaces mean fewer sources of error. In this valve the whole pilot path stays inside, controlled over 4...20 mA. The main spool releases 220 l/min nominal flow, the limit being 870 l/min at 350 bar.

Benefits

• Pilot oil supplied internally, drained internally, only the four working ports sit outside
• Current command 4...20 mA, insensitive to line resistance
• 220 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
• Spool symbol W6, 3 switching positions, concealed manual override
• FKM seals for HL fluid, UKCA to SI2016/1091, size 25 at 20.24 kg

Applications

The build suits enclosed power units, container plants as well as workshop rigs where every extra line is in the way. A return line with low back pressure remains the precondition. Porting follows the ISO 4401-08-08-0-05 pattern of size 25.
