Bosch Rexroth 4WMM6JA5X//V manual directional valve

4WMM6JA5X//V, manufacturer material number R900372646, is a Bosch Rexroth size 6 direct-operated directional spool valve with hand-lever actuation and spool symbol JA. The published execution uses spring return when the hand lever is released.

The 315 bar P/A/B rating and 160 bar T rating are separate limits. The 60 L/min catalog maximum is subject to the selected spool operating envelope; values for special fluids can be lower.

The mounting interface is a subplate pattern, not a threaded fluid fitting. Subplates and mounting screws are separately selected; the original pages show the applicable interfaces and installation requirements.
