Often the extra initial cost of the valve can be paid for in a matter of days. As a result of studies such as these, the process industries have become increasingly aware that control valve assemblies play an important role in loop/unit/plant performance. They have also realized that traditional methods of specifying a valve assembly are no longer adequate to ensure the benefits of process optimization. While important, such static performance indicators as flow capacity, leakage, materials compatibility, and bench performance data are not sufficiently adequate to deal with the dy- Chapter 2.

Stiction: the force required to cause one body in contact with another to begin to move. Supply Pressure*: The pressure at the supply port of a device. Common values of control valve supply pressure are 20 psig for a 3 to 15 psig range and 35 psig for a 6 to 30 psig range. Zero Error*: Error of a device operating under specified conditions of use when the input is at the lower range value. It is usually expressed as percent of ideal span. 21 Chapter 1. Introduction to Control Valves 22 Chapter 2 Control Valve Performance In today’s dynamic business environment, manufacturers are under extreme economic pressures.

A quality product conforms to a set of specifications. Any deviation from the established specification means lost profit due to excessive material use, reprocessing costs, or wasted product. Thus, a large financial impact is obtained through improving process control. Reducing process variability through better process control allows optimization of the process and the production of products right the first time. The non-uniformity inherent in the raw materials and processes of production are common causes of variation that produce a variation of the process 23 Chapter 2.
