Abhiroop,

Take a look at these 2 papers :

"A Novel Flow Control Valve for Pulsating Flows"

http://people.eng.unimelb.edu.au/imarusic/proceedings/19/370.pdf

"Pulsating Flows : Experimental Equipment and Its Application"

Best regards

If You can open and close the valve with exact frequency you may achieve what you need but avoid high force which may disturb the flow.

Use a valve which is easy to rotate.

Let me split this question into two part,

First one, Can valves control the flow rate in a piping system ?

The answer is Yes. Globe valves are used to control the flow rate. Globe valves are like control valves, but require to be operated manually i.e. A globe valve with actuator becomes a Control Valve, though control valve has some additional parameters in designing it.

The second one is How we can do that ?

All valves have a “gate”, which throttles the flow. In case of Globe valve it is smooth throttling ( the operating wheel can be adjusted to control the flow rate i.e. to increase & decrease the throttling) and very effective. Gate valves are generally used for STOP & START operations. Check valve to contain reverse flow of process liquid. Ball valves are quarter turn valves, used where fire-safe design is required (quick opening & closing).

I hope this helps

Regards

thank you
