,Manual ValvesAutomated valves refer to those that use automation methods like pneumatic, hydraulic, and electric control systems to mechanically or electrically operate the valve in order to control the flow of fluid. They are typically used in industries such as petroleum, chemical, pharmaceutical, food and beverage, and many others that require precise control of the flow of substances. Automatic valves are also used for controlling water pressure and temperature in residential, commercial, and industrial settings.Manual valves, on the other hand, are manually operated using a physical force such as a handle, knob, lever, or other type of device. These valves are widely used for general purposes, often seen in residential settings for the purpose of controlling plumbing (water, sewage, etc.). They are also commonly used in industrial processes where manual access to the valve is convenient or necessary. Additionally, manual valves can be applied in safety systems so that manual intervention is available in the event of a failure in the automated controls.
