On top of the mechanical motion involved with a valve also consider the method of actuation. In most cases valves fall into one of three categories: Manual Valves: Typically adjusted by hand these valves use handwheels hand levels gear wheels or chains to actuate. Actuated Valves: Often connected to electric motors air or pneumatic systems hydraulic systems or solenoids …
