Product_description: ['A valve is a device that regulates directs or controls the flow of a fluid (gases steam liquids fluidized solids or slurries) by opening closing or partially obstructing various passageways. Valves are technically fittings but are usually discussed as a separate category. In an open valve fluid flows in a direction from higher pressure to lower pressure. These changes may act upon a diaphragm or a piston which in turn activates the valve. They can be electromechanical actuators such as an electric motor or solenoid pneumatic actuators which are controlled by air pressure or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water.
