Supervisory Control and Data Acquisition Systems for Pneumatic and Electrical Actuated Knife Gate Valves

Automation in all fields is picking up pace due to its inherent ability to complete a given piece of work much quickly and efficiently as compared to manual work which although skilled, requires greater lead time and may lead to reduction in productivity. Industries which are mainly concerned with energy conversion are obsessed with the maximum utilization of the exergy to get the most efficient outputs. Technological advancement in the field of mechatronics and microprocessors has led to continuous up gradation in the systems that govern and control such applications. Valves are an integral part of any flow system. In order to have a wider control over operations of large energy conversion units, supervisory control and data acquisition systems are employed. This paper shall consider scope of the same for applications employing actuated Knife Gate Valves. The actuation considered shall be pneumatic type which generally comprises of a double acting pneumatic cylinder. Considerations for controls and data acquisition shall be done for pneumatic circuit accessories like solenoid operated direction control valves of various types, limit switches, proximity switches and electro pneumatic positioners with an initial explanation of role and working of each. A conclusion shall be drawn thereafter regarding the employability of knife gate valves with supervisory control and data acquisition systems.
