Abstract
Today the performance requirements of process plants are becoming increasingly difficult to satisfy. In fact, without process control it is difficult to operate most modern processes safely and profitably. To understand the process dynamics and its behavior Apex has developed compact setups. These setups are easy to operate and self-educative. Some of the products are computerized and work with specially developed interactive software. We hope one will find the theoretical knowledge in its best practical performance with the Apex products. The control valve characteristic set up is designed to understand basic principles and operation of pneumatically actuated control valves. The stand-alone type set up consists of different type of control valves, cylindrical overhead tank, receiving tank, rotameter, pump and other components mounted on supporting structure.
