 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.
