The HI-100 product line features an in-line, through-ported, venturi flow shape. The seating element, a ball, is contained by a cage that positions it relative to the downstream seat by means of linear stem travel. There are no close clearances between the moving parts (i.e. cage, ball, and seat). These basic features enable the valve design to operate smoothly and efficiently at high or low temperature, and/or with fluids containing foreign matter such as slurries. The HI-100 operates in the full open position, the throttling position and the closed position.

It is important to note that all valves have a guide pin. This pin is used only to position the ball for closing when there is insufficient flow to create an adequate pressure differential. When the valve is operating with a sufficient differential across the valve, the guide pin has no function.
