Directional Spool Valve 4WEH32C6X/6EG24N9TK4/11B08 - Bosch Rexroth R901070117

As a large main spool opens, inlet pressure dips for a moment and the pilot stage should not notice. The 4WEH32C6X/6EG24N9TK4/11B08 is therefore supplied with pilot oil externally and drained internally through the tank channel.

Benefits

• External pilot oil supply, internal pilot oil return, keeping the pilot stage fed when inlet pressure dips.
• 1100 l/min maximum flow in size 32.
• Spool symbol C with 2 switching positions and 4 ports to ISO 4401-10-09-0-05.
• 280 bar maximum operating pressure with HL hydraulic fluid and NBR seals.
• Control on 24 V DC through a 3-pole (2 + PE) connector to EN 175301-803.
• 35.74 kg weight in size 32.

Applications

The valve belongs in the main circuit of large presses and power units whose pump pressure dips at the moment of reversal. A separate pilot source keeps switching times repeatable. Mounting is on a size 32 subplate.
