Control Valves

The control valve is a critical part of the control loop. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keeps the regulated process variable as close as possible to the desired set point.

Types:

• Ball valve
• Butterfly valve
• Plug valve

2-Flow control valves:

• Gate valve
• Globe valve
• Diaphragm valve
