IND-PTV - Control Valves

The video tutorial explains the functioning of valve actuators, which move valves to desired positions using external power sources like pneumatics, electronics, or hydraulics. It details pneumatic actuators, which use air pressure for linear or rotary motion, and electric actuators, which convert electricity to mechanical energy. Hydraulic actuators, using pressurized fluid, are also discussed for their speed and power. The tutorial covers different types of actuators, their mechanisms, and methods of operation.
