Directional Spool Valve 4WEH16E7X/6EG24N9ETK4/B10P4,5 - Bosch Rexroth R900943549

Every extra pilot line on a manifold is one more place to leak. The 4WEH16E7X/6EG24N9ETK4/B10P4,5 avoids them, feeding and draining its pilot stage internally and holding pilot pressure through a 4.5 bar pre-load valve. A main circuit may still carry up to 300 l/min at 280 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no external X or Y line.
• 4.5 bar pre-load valve secures pilot pressure in an unloaded circuit.
• Spool symbol E in three switching positions across four ports.
• Up to 300 l/min at a maximum of 280 bar, hole pattern ISO 4401-07-07-0-05.
• 9.9 kg, 24 VDC and a 3-pole connector (2 + PE) to EN 175301-803.

Application

It suits compact manifolds in presses and power units where only P, T, A and B are to be piped. Because both pilot paths run internally, a subplate stays free of extra fittings.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16E7X/6EG24N9ETK4/B10P4,5 under material number R900943549. Data sheets RE 24751 and RE 07600-B show characteristic curves, installation dimensions and the connection diagram.
