CV values Product Group 200 Butterfly Valves
Rated flow coefficient (Cv) is a number which represents a valve's ability to pass flow.The bigger the Cv, the more flow can pass through the valve at a given pressure drop. The Cv value means the volume of water inUS gallons per minute that passes through a given valve opening with a pressure drop of 1 pound square inch (Water at 60°F)
A Cv of 1900 means a valve will pass 1900 US gpm water of 60°F at a Dp of 1 PSI.
The relation between Cv and Kv, expressed in the above mentioned unit of measure are as follows
Cv=1.16kv
Formula 1FLOW RATE LBS/HR(Steam or Water)
Where :dp = pressure drop in PSIF = flow rate in lbs /hr.

Torque figures as mentioned in the torque table below are;· Initial break away values in Nm (Newton Meters)
· Excluding any safety factor · For valves that are operated at least once per month
· Temperature 0 to 50 degr. C
Safety factor (sf)
For sizing and safe operation purposes the specified torque values needto be multiplied with the following minimum safety factors;
· For liquid and lubricant media sf = 1.25 · For powdery (non-lubricant) media sf = 2.00
· For dry gasses and high viscous media sf = 2.00
For assistance in sizing and dimensioning actuator-valve combinations please contact our Engineers.We have wide experience in sizing Pneumatic, Electric and Hydraulic actuators.
