DFT HI-100
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.
Key design features:
High Flow Capacity
Straight Through Non-Turbulent Flow
Tight Shut-Off
Wide Rangeability
Less Susceptible to Erosive and Abrasive Wear
High Pressure-Temperature Capabilities
Low Operating Thrust

DFT ULTRA-TROL®
The ULTRA-TROL® is designed for applications requiring flanged end connections. The internal design features are similar to the HI-100 found on page 6. They include the in-line through ported, venturi flow shape and the contained spherical ball. The ball, cage and stem can easily be replaced in-line through the bottom cover without removing the valve from the line. The downstream seat is end loaded for quick replacement. Like the HI-100, the ULTRA-TROL® can be used for various fluids including slurries in high or low temperature applications for refining, chemical, petrochemical and co-generating facilities.
