Hello everybody,
I have a flow control valve which has a Cv = 0.1 and controls the flow of staurated steam. Because this is not a flowmeter, I am trying to infer the flow passing through this valve according to the pressure drop across it. As I said, my fluid is 300F saturated steam and I am...
Hi,
I am trying to choose a flow control valve but I do not understand the meaning of "Cv" and what that stands for. Is this a characteristic of the valve? How do I read the flow range of a specific Cv valve. I am asking that because I need to choose a valve with a specific Cv but do not know...
This is a very basic question but it has been raising many doubts here, amazingly.
How do I transform a flow of lbs/h of steam in cubic feet per minute (or if you prefer cubic meters per second). Could anyone please indicate me the formula and if that would be dependent on the temperature of the...
Hello,
I have a fluidizing rig which uses steam as the fluidizing gas and nitrogen as a inert gas at the upper part of the same rig. The temperature of the steam is 600°C and the nitorgen is at 220°C. The steam flows upward at 180 liters/min and the nitrogen downward at 70 liters/min (they both...
Hello everybody,
I have a low flow control valve with the following characteristics:
Cv = 0.1
Range: 4-20
I am not a valve expert so I don't understand this terminology and I am trying to read the flow from this valve. I not even know what is the flow unit in this case (cubic feet/min...
Hello,
We are designing a steam line and some debate has been risen regarding the amount of water that will supply our steam demand. We know how much steam we need to run our application (liters/hour), according to a specific flow that we need inside the equipment tha uses it, but the question...
Hello Everybody,
I am about to start some testing on cylindrical samples (2cm diameter x 10cm length) that are subject to wear in a fluidized bed and I am looking for a profilometer for my mesurements of the wear rate on those samples. I have been looking around but it's been hard to find some...

This is the first time I am working with steam and I must build a line where I must generate steam at a temperature of 600C. My application requires low flow rates (4kg/h) and the dry steam must be introduced into my system at atmospheric pressure. Is it possible to generate superheated 600C...
