In case of installing a valve we must know it’s functions, we must know if it is able to prevent backflow, start the flow, stop the flow, regulate flow, or regulate pressure. How to install a control valve and what are the factors that must be considered while installing a control valve
They have low recovery and can throttle small flow rates.All of these valves have their own special features which could either be an advantage or disadvantage for the given application. While the rotary motion control valves consist of ball, butterfly or plug closures. What are the types of control valvesĬontrol valves are classified into linear and rotary, linear motion control valves are comprised of globe, gate and diaphragm type closures. Control valves will provide the required energy to the controllers. The control valve is the final control element, it is the major part of the automatic control. Automatic control of the modern plants is done with the help of control valves they can do an exchange of energy and reduction of pressure. Control valves are used in the fluid power system.
Control valves are used in gas centrifugal compressors to avoid damages in the compression machine. They are controlled so that the load disturbance can be compensated. Control valves are used to control the flow and direction of fluid such as gas, water, steam or chemical compounds.
