Directional Spool Valve 4WEH16HE7X/6EG24N9EK4/B08 - Bosch Rexroth R900973999

A valve with three switching positions must return cleanly to centre even when pressure stands in the tank channel. The 4WEH16HE7X/6EG24N9EK4/B08 therefore drains its pilot oil externally while being supplied internally, controlling 300 l/min to symbol E.

Benefits

• Internal pilot supply with external drain, the reset stays independent of back pressure.
• Three switching positions to symbol E across four ports.
• 300 l/min rated flow, maximum operating pressure 280 bar.
• 10.36 kg, size 16, NBR seals for hydraulic fluid HL.
• 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803.

Application

In systems with a return filter or an oil cooler a pressure builds up in the tank channel that hinders the spring centring of the pilot stage. The external Y drain routes the pilot oil past it. The axis therefore reaches its relieved centre position even under full return load.
