Directional Spool Valve 4WEH16E7X/6EG24K4/10 - Bosch Rexroth R901120927

So that a tool can retreat by itself after the cycle, both service ports must be open to tank. The 4WEH16E7X/6EG24K4/10 provides this centre position to symbol E and works with an externally supplied pilot circuit.

Benefits

• Centre position to symbol E, both service ports are relieved.
• 300 l/min rated flow, maximum operating pressure 280 bar.
• Pilot oil supplied and drained externally, separated from the main circuit.
• 10.3 kg, size 16 on interface ISO 4401-07-07-0-05.
• 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Application

In forming machines and clamping fixtures the cylinder has to lose pressure quickly after the working stroke so the workpiece can be removed. The relieved centre position does this without an extra unloading valve. At 300 l/min the pressure also decays swiftly in large chambers.
