Gas flow control valve

A compact gas flow control valve has a valve body having an inlet for receiving gas pressure, to provide gas at a substantially constant delivery pressure to be delivered by the gas flow control valve, and an outlet for delivery of the gas. Flow rate of the delivered gas is controlled by a rotor. A...

Zusammenfassung:A compact gas flow control valve has a valve body having an inlet for receiving gas pressure, to provide gas at a substantially constant delivery pressure to be delivered by the gas flow control valve, and an outlet for delivery of the gas. Flow rate of the delivered gas is controlled by a rotor. A flow control plate covering the rotor has a plurality of orifices produced by one of various processes including mechanical drilling, laser drilling, piercing, punching, and selective etching. A selector mechanism orients the rotor to permit flow only through a selected one of said orifices at such delivery pressure for delivery by the outlet. The orifices define a preselected schedule of different flow rates determined by the diameter of the respective orifices.
