Note: Final material selection should be based off duty cycle.
Note: Recommended flow is calculated using ~15 ft/sec oil velocity on the common T gallery. The velocity out each station pad will be higher although it is wihtin the recommended directional valve manufacturers specs. Note that depending on the relief valve response a shock pressure could be generated if the velocity is too high.
