Directional Spool Valve 4WEH16R7X/6EG24N9ETSK4/B10 - Bosch Rexroth R901252939

A separate pilot circuit only pays off on larger installations. Pilot-operated directional spool valve 4WEH16R7X/6EG24N9ETSK4/B10 does without one, since pilot supply and pilot return both run internally, while carrying 300 l/min at up to 280 bar.

Benefits

• Internal pilot oil supply, internal pilot oil return, no separate pilot circuit needed.
• Spool symbol R, three switching positions across four ports.
• 300 l/min in size 16 at a maximum of 280 bar.
• 10.88 kg, interface ISO 4401-07-07-0-05.
• Solenoid actuation on 24 V DC, connector 3-pole (2 + PE) according to EN 175301-803.

Application

Valves like this sit in power units of rolling mills, punching machines and test rigs that run on one pressure circuit. Internal pilot routing cuts the number of fittings and with it the number of possible leak points. For replacement, interface, symbol and material number are what count.
