Directional Spool Valve 4WEH10E4X/6EG24N9SK4 - Bosch Rexroth R900964481

When supply voltage fails, it has to be clear where a spool travels. The pilot-operated directional spool valve 4WEH10E4X/6EG24N9SK4 then takes its centre position to spool symbol E and in service carries up to 160 l/min at a maximum of 280 bar.

Benefits

• Spool symbol E in three switching positions with a defined centre position.
• Up to 160 l/min at a maximum of 280 bar, size 10 with an ISO 4401-05-05-0-05 hole pattern.
• External pilot oil supply and external pilot oil return through ports X and Y.
• 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803.
• 8.36 kg with NBR seals for HL hydraulic fluid.

Technical data

Application

It goes into manifolds on presses, clamping units and power packs where a cylinder must reach a known position at shutdown. An external pilot circuit feeds a pilot stage independently of working pressure.
