Amot 3-Way Control Valve, Amot Model GE and GP

Valves are tested for flow rate versus valve opening using a constant pressure drop to determine the valve’s inherent flow characteristic. These are usually categorized as equal percentage, linear or quick opening. Most industrial processes use equal percentage type valves due to how the process varies as the flow varies. Butterfly and ball valves are … Read more

Pneumatic valves angle seat operated valves

Champagne and Boyle reviewed the pneumatic actuator and positioner parameters that affect the control package performance. This was done through the use of a control valve package computer model to assess the dynamic performance. The attributes of spring return versus double-acting actuators were illustrated.Pneumatic ball valves generally have a lower purchase price than electric ball … Read more
