Directional Spool Valve 4WEH16R7X/6EG24N9K4 - Bosch Rexroth R900929283

A separate control circuit pays off as soon as several valves are piloted together. The 4WEH16R7X/6EG24N9K4 takes both supply and return of the pilot oil from outside and keeps the main circuit clear of them. Symbol R switches at up to 300 l/min and 280 bar.

Benefits

• External pilot oil supply and external return, version 6EG24N9K4
• Symbol R in three switching positions with four ports
• Up to 300 l/min at a maximum operating pressure of 280 bar
• Subplate mounting ISO 4401-07-07-0-05 in size 16
• 24 V DC solenoid with a 3-pole connector (2 + PE) to EN 175301-803
• NBR seals, HL hydraulic fluid, weight 9.86 kg

Application

Plants carrying several directional valves on one manifold often run the pilot oil from a dedicated source. The external return keeps the pilot pressure clear of back pressure in the return line. Typical places are the power units of presses and test rigs rated at 300 l/min.
