Regulators are a lot like Rodney Dangerfield, they “don’t get no respect!”  How often are industrial regulators the topic of water cooler conversations?  How many of you learned about regulators as part of your college curriculum?  I cannot see the show of hands but have to believe it is a pretty small number, if any.  My career in the valve industry began when I first walked into a valve manufacturing facility in 1979 and, until seven years ago, all my valve experience focused on quarter turn products with a sprinkle of multi-turn rising stem valves thrown in.  I knew of regulators but did not know how they operated or where they were applied.

Accurate regulation.  This depends on the type of regulator, i.e., self operated, pilot operated, or dome loaded, and the manufacturer’s design.  Droop, often referred to as Offset, is an inherent characteristic of all self-operated and pilot operated regulators.  Droop is defined as the drop in (controlled or reduced) pressure (P2) as the valve moves from the minimum flow position to the maximum flow position.   This deviation from set point is expressed as a percentage.  Regulator accuracy is the inverse of droop.  If a regulator has a 10% droop, the regulator is 90% accurate.  The lower the droop, the more accurate the regulation.

Fast response.  This depends on stroke length.  Regulators respond very quickly because they operate of the medium being controlled.

Tight shutoff.   Normally ANSI Class IV shutoff is acceptable as the regulator is controlling pressure and temperature and ideally operates between 30% and 70% open.  Tighter shutoff, Class VI, is a requirement in some gas applications.  ANSI Class III or IV shutoff is available in most metal seated regulators, while Class VI may be available in soft seated models.

When my formal introduction to regulators began, I was fascinated by their simple, elegant design and exceptional performance.  How do they work?  No electric, no air, no operator!  Wow!  I may be a little more enthusiastic than most, but there are some very compelling reasons to consider using a regulator for your pressure or temperature control needs.
