Directional Spool Valve 4WEH16H7X/6EG24N9TK4/B10 - Bosch Rexroth R900977135

A main circuit that idles at zero pressure no longer feeds an internal pilot stage. The 4WEH16H7X/6EG24N9TK4/B10 therefore takes pilot oil externally and drains it internally, at up to 300 l/min and a maximum of 280 bar.

Benefits

• External pilot oil supply, so the valve still shifts while the main circuit runs unloaded.
• Internal pilot oil return, one line fewer on the manifold.
• Spool symbol H in three switching positions across four ports.
• 300 l/min at a maximum of 280 bar in size 16, weighing 9,78 kg.
• 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803, NBR seals.

Application

Systems with an unloading circuit or a dedicated pilot pump benefit from this version. Pilot pressure is then independent of working pressure and shifting times stay the same at idle. The subplate interface to ISO 4401-07-07-0-05 fits common size 16 plates.
