The DFT® HI-100® is a severe service control valve that can handle a wide variety of fluids, from gases and liquids to light slurries, as well as high pressures and a wide range of temperatures. Our unique straight-thru Venturi design performs in the harshest applications. A key feature of this valve is maintenance can be performed in-line without expensive tools using our quick-change trim.

Designed for High Maintenance Environments

Refinery and chemical applications include:
Abrasive slurry control, amine service, butadiene service, pitch blending, sour water, and quench water control. The presence of a Bernoulli pressure differential through the valve prevents suspended particles from collecting in the valve body. This keeps the valve clean and free of material deposits. Any suspended particles flowing through the venturi concentrate in the center of the fluid stream to minimize the erosive action of the fluid on critical valve services.

Power plant applications include soot-blower, attemperator spray letdown, feedwater control, boiler feedwater recirculation, drum level control, turbine drain, wet steam, and high-pressure reduction.

The HI-100® features the control element, a spherical ball, 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 features enable the valve to operate smoothly and efficiently at high or low temperatures, and/or in fluids carrying suspended particles such as slurries. The Quick Change Trim feature permits in-line replacement of the internal trim (ball, stem, cage, seats, seat retainer cartridge and wear bushings). Interchangeability of the upstream and downstream seats and wear bushings extend the life of the valve at no extra cost.
