Hans recommends WHAT TO LOOK FOR IN A GOOD CONTROL VALVE DESIGN
Besides the obvious, such as good quality workmanship, correct selection of materials, noise emission, etc., special attention should be paid to two areas: • Low dead band of the actuator/valve combination (with tight packing). • Tight shutoff, in cases of single-seated globe valves and some rotary valves (if required).

Hans recommends WHAT NOT TO DO WITH CONTROL VALVES
1) Install a steam valve at the bottom of a down-header. 2) Install a steam valve at the bottom of a down-header without providing a steam trap near the inlet side of a valve. 3) Locate a condensate return valve more than three feet away from a flash tank or condenser. 4) Buy a cage-trim valve for elevated temperature service without elastic support between cage and bonnet 5) Buy an I/P transducer with a 3-15 psi output signal when the actuator spring of the valve is also 3-15 psi and there is no positioner.

More about Hans Baumann and the Book
This book includes insights on valve sizing, smart (digital) valve positioners, field-based architecture, network system technology, and control loop performance evaluation. Baumann, a holder of more than 150 patents, and author of over a hundred publications in control valve technology, shares his expertise on designing control loops and selecting final control elements. The easy-to-read text provides shortcuts through complex sizing and noise calculation formulas including for liquids and cavitation, and gives practical advice on how to apply control valves for safety, reduced energy costs, loop stability, and more.
