Test Stand for Control Valves

Model HV-EXP4446
Technical Description Control valves are an essential part of  process and chemical engineering. The connection between controller and  plant is realised with control valves as actuators. Control valves are  usually used to regulate flows of gases or liquids. Optimum control loop design depends on a sound knowledge of control valve behaviour as well  as a knowledge of the controlled systems response. This mobile test stand allows to investigate and study control valves of different  types. For this purpose the valve is installed in a closed water circuit with a pressure pump and a supply tank. Flow rate and pressure drop  across the valve are measured. The trigger signal is generated by  potentiometers and indicated on a display. Electrically operated motor  valves can be investigated as well as pneumatic control valves. A data  acquisition system can be used to record and evaluate characteristics  and step responses on a PC.
