The next evolution in DRAG® technology The High Turndown Ratio (HTR) trim is the next evolution in DRAG® technology. This technology can drastically reduce the amount of valve cycling and increase the accuracy of the temperature control, resulting in an improvement of plant heat rate, efficiency, and overall reliability.

The precision of the design and manufacturing of HTR DRAG® allows for tight control of flow passages, significantly increasing the turndown capability and improving overall process control. When compared to competitor multi-stage cage designs, HTR DRAG® provides more precise control of temperature at low valve lifts without sacrificing high valve lift performance.

Precise control = dramatically improved plant efficiency.
Ultra-high turndown = faster plant start-ups.
Multi-stage velocity control = extended valve trim life.
Direct replacement for existing 100DSV and DA90-DSV DRAG® disk stacks.
