Abstract

Valves are elements of the pipe through which fluid flow is controlled, directed and regulated permanently. A single type of valve cannot fulfill all these functions (control, steering and adjustment), which is why there is one type of valve for each function. Four types of actuators can be attached to valve’s body rod: 1) Spinning wheel (manual device); 2) Pneumatic actuation (device driven by air pressure); 3) Electric actuation (device powered by electric current); 4) Hydraulic actuation (device driven by hydraulic oil pressure). Valve actuators improve control, accuracy and efficiency. Despite higher capital and operating costs, the actuators are frequently cost-effective in oil and gas industry where automation is a necessity due to remote, dangerous areas, unmanned installations. Electric actuator can be controlled remotely from a control center. More than 1 million actuators are in use around the world, some being in operation for more than 50 years. Reliability is primary reason for selection of those type of actuators. Searches related to data published by European Industrial Forecasting Ltd. (EIF) in 2015, shows that nearly 75% of all valves in the oil and gas sector are automated, compared to just 30% across all industries combined.
