Too often, pneumatic circuits are sized based on the valve’s flow coefficient, C v, without considering other system components. In the past, focusing on the valve alone often sufficed because air was ...

I am disappointed every time I see the flow coefficient C v used to size a valve without consideration given to the other components in a pneumatic circuit. In the old days, a focus on the valve alone ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...
