WebFlow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve. Flow coefficient is an imperial measurement and is defined as: the flow of water through a valve at 60°F in US gallons/minute (gpm) at a pressure drop of 1lb/in². Flow factor is the metric equivalent of flow coefficient and is ... WebApr 11, 2024 · For example, a 2/2-way pneumatic valve is a valve that has two switching positions and two ports. A 3/2-way valve is a two position valve with three ports. By extension, a 4/2-way valve represents a valve that has two switching positions and four ports; a 5/2-way valve has two switching positions and five ports.
