7. Major applications Used in control systems to regulate flow of gases, liquids, fluidized solids, and slurries by opening and closing passageways. In industry majority are used with oil and gas, power generation, mining, water control, sewage, and chemical manufacturing 5/23/2015 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Slide-7

8. Basic Working Principle Control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point (Control Valve Handbook). 5/23/2015 ECE5320 Mechatronics.

9. Types of Control Valves Electric valve Globe valve Air powered valve Angle seat piston valve Rotary valves Sliding cylinder valve Solenoid valve 5/23/2015 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Slide-9 http://en.wikipedia.org/wiki/Control_valves Globe Valve

10. Sample Configuration Use of control valve to control lubricant/coolant going to milling machines at a manufacturing plant –The valve opens when the machine requests some coolant to start milling –The coolant/lubricant will be held in holding tanks when it isn’t used –Makes milling more efficient and reduces the amount of wear on milling tools 5/23/2015 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Slide-10

12. Limitations Valves are limited on the following factors: –Flow rate –Number of Ports/Ways –Connection –Material –Maximum temperature allowed –Pressure rating 5/23/2015 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Slide-12

13. Flow Characteristics Trim design of valve effects how the control valve capacity changes as the valve moves through its complete travel Control valve flow characteristics shows how the linearity changes 5/23/2015 ECE5320 Mechatronics.

20. Conclusion Control valves are essential for controlling multiple medias in industry. Help save a lot of money by only providing different medias when they are needed, instead of constantly. Are simple to understand and to implement. 5/23/2015 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Slide-20
