Directional Spool Valve H-4WEH25C6X/6EG24N9K4/B08 - Bosch Rexroth R900957517

Behind return filters and coolers the tank passage often carries more pressure than the pilot circuit tolerates. This version therefore takes the pilot oil return outside and keeps working with a loaded tank passage.

Benefits

• External pilot oil return, independent of back pressure behind filter and cooler.
• External pilot oil supply from a separate circuit, solenoid actuation at 24 VDC.
• Spool symbol C with 4 ports and 2 switching positions.
• Flow up to 700 l/min in size 25, maximum operating pressure 350 bar.
• 17.32 kg weight, subplate mounting ISO 4401-08-08-0-05, NBR seals.

Application

Installation pays off in systems with a long return line, a cooler or a fine filter in the tank branch. Switching behaviour stays stable there because the pilot circuit uses its own paths. A 3-pole connector (2 + PE) to EN 175301-803 serves for the electrical connection.
