This dramatically increased the linear range of operation of the nozzle and flapper amplifier, and integral control could also be added by the use of a precision bleed valve and a bellows generating the integral term. The result was the "Stabilog" controller which gave both proportional and integral functions using feedback bellows. [5]
Robert Henry Abplanalp, (April 4, 1922 – August 30, 2003) was an American inventor and engineer who invented the modern form of the aerosol spray valve, the founder of Precision Valve Corporation, a Republican political activist, and a close confidant of Richard Nixon.

The balls rise as speed increases, which closes the valve, reducing speed until a balance is achieved. Proportional control , in engineering and process control, is a type of linear feedback control system in which a correction is applied to the controlled variable, and the size of the correction is proportional to the difference between the ...

A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s , e.g. water.
