Directional Spool Valve 4WEH16HJ7X/6EG24N9S2K4 - Bosch Rexroth R900779493

Replacing a fitted valve calls for a match in spool symbol, pilot oil routing and voltage, otherwise the plant behaves differently from what was planned. This build carries symbol J in three switching positions and routes both pilot feed and pilot return to the outside. It runs at 24 VDC with flows up to 300 l/min and a maximum of 280 bar.

Benefits

• Spool symbol J with three switching positions on four ports
• External pilot oil supply and external pilot oil return
• Flow up to 300 l/min, maximum operating pressure of 280 bar
• Subplate mounting to ISO 4401-07-07-0-05 in size 16
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Mass 11.2 kg, NBR seals for HL hydraulic fluid

Application

In maintenance, matching symbol, pilot routing and voltage decides whether the plant works as before after the swap. The ISO 4401-07-07-0-05 hole pattern alone is not a sufficient criterion. The full type designation is stamped on the nameplate of the valve being removed.

Manufacturer
