Directional Spool Valve 4WEH16J7X/6EG24N9K4/B08 - Bosch Rexroth R900925894

Separating the pilot stage from the working circuit lets pilot pressure be measured on its own. The 4WEH16J7X/6EG24N9K4/B08 feeds and drains pilot oil externally, shifts to spool symbol J and lets through up to 300 l/min at a maximum of 280 bar.

Benefits

• External pilot oil supply and external pilot oil return, the pilot circuit can be checked on its own.
• Spool symbol J, three switching positions, four ports in size 16.
• 300 l/min at a maximum operating pressure of 280 bar.
• 9,79 kg, subplate mounting to ISO 4401-07-07-0-05.
• 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803, NBR seals for HL hydraulic fluid.

Technical data

Application

Machines running several axes usually feed pilot oil centrally, which makes this the fitting version. During a fault, a gauge in the pilot line shows at once whether the problem sits in the pilot stage or the main circuit. Four ports serve one double-acting cylinder.
