Directional Spool Valve 4WEH16H7X/6EG24N9EK4K/B10P4,5 - Bosch Rexroth R901211793

When the main circuit supplies enough pressure, pilot oil can be tapped internally and a separate pilot pump becomes unnecessary. The 4WEH16H7X/6EG24N9EK4K/B10P4,5 uses internal pilot oil supply with external return and switches up to 300 l/min.

Advantages

• Internal pilot oil supply removes the need for an extra pressure source for piloting.
• Three switching positions across four ports, with the middle position following symbol H.
• Maximum operating pressure of 280 bar at a flow of up to 300 l/min in size 16.
• External pilot oil return can be routed to tank without back pressure.
• Weight of 9.8 kg on the ISO 4401-07-07-0-05 connection pattern.

Application

The valve controls lifting and closing axes in presses and power units whose working pressure is permanently high enough for piloting. Pilot oil return is routed separately to tank. The solenoid runs on 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803.
