The 200 Series non-lubricated selector valves are designed to operate in systems where instantaneous port selection is desired. Since lubricants are not used, re-lubrication is not required. There is no lubricant to freeze and lock the valve or to contaminate fine fluids. The O-ring sealed cap and stem eliminate leakage.  Designed for panel or bracket mounting. Standard with pointer lever and an audible click mechanism.  This arrangement assures proper porting selection by sound or touch.  This construction is highly desirable when the operator's visual attention cannot be distracted or for remote valve locations.  The valve rotates 360 degrees with click intervals spaced every 90 degrees.
