Supplemental Guide Directional Control Valve Products Interflow and Non-Interflow in Barksdale Valves Interflow in a Barksdale Shear-Seal® valve is a small amount of fluid flow from the Pressure A and B ports to the return port through the clearance between the rotor and the body. This interflow occurs whenever the valve is shifted from one position to another or when the valve is being used for throttling. This is due to the Shear-Seal® in the valve being only partially covered by the rotor. Interflow is not leakage and does not occur when the valve is fully engaged. The interflow in a...

Supplemental Guide Directional Control Valve Products Pressure Drop Curves (Theoretical) Pressure Drop Barksdale’s Shear-Seal® Valves have a much lower pressure drop than other valve technologies. This is possibly due to smooth internal passages and transitions within the valves which keep turbulent fluid flow to a minimum. This translates to less heat build-up and higher pressures available to perform the required work. Determine Pressure Drop for Barksdale Shear-Seal Valves 1. Determine the Rate of Flow in G.P.M. or L.P.M. for fluid being controlled. 2. Determine minimum flow passage for...

Supplemental Guide Directional Control Valve Products Velocity Curves (Theoretical) Fluid Velocity Barksdale’s Shear-Seal® Valves control fluid at a much higher velocity than other types of valve technologies. This means that a smaller valve can be used to do the same types of job, saving you space and component costs. The recommended velocity for Barksdale valves is about 30 ft/sec (9.1 m.sec) for continuous operation. However, the valve can easily handle higher velocities up to 60 ft/sec (19.3 m/sec) for intermittent duty. Determining Fluid Velocity in a Shear-Seal Valve for a known Rate...
