Directional Spool Valve H-4WEH25E6X/6EG205N9TK4 - Bosch Rexroth R900973092

Pilot pressure comes from outside, pilot oil returns inside the valve: this split suits power units with a short, unloaded tank path. The H-4WEH25E6X/6EG205N9TK4 implements it in size 25, at 700 l/min and 350 bar maximum operating pressure.

Benefits

• Pilot oil supplied externally, drained internally, secured pilot pressure without an extra return line.
• 205 VDC supply voltage through a 3-pole (2 + PE) plug to EN 175301-803.
• Spool symbol E with three switching positions across four ports on the ISO 4401-08-08-0-05 pattern.
• 700 l/min flow at 350 bar maximum operating pressure in size 25.
• 18.31 kg weight, NBR seals for HL hydraulic fluid, UKCA conformity to SI2016/1091.

Technical data

Applications

The valve is used in control manifolds of presses and lifting gear whose tank connection is short and unloaded. The internal return cuts pipework without giving up the secured pilot pressure. Where the return carries back pressure, use the version with an external pilot drain.
