For any specific valve opening with an equivalent pressure drop and equivalent temperature, by applying multiplication factor we get equal flows in both imperial and metric units. Flow coefficient c v ——it is the full capacity flow rate through the valve in us gallons/min. Flow coefficient information scope ——the values given below are applicable to floating ball valve/tru nnion mounted ball valve, when the ball valve is in full open condition. Valve sizing calculations (traditional method) 626 technical introduction fisher® regulators and valves have traditionally been sized using equations derived by the company.

In metric units, the same valve above with a specified opening giving cv = 1 will pass 0.862m3/hr of water (at 15 degree celsius) if 1bar pressure difference(δp) exist between upstream and downstream points on each side of the valve. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as: For a specific control valve, flow coefficient cv/kv is determined experimentally by control valve manufacturers, and you can found it in manufacturers technical specifications. For example, you can calculate required control valve capacity (cv or kv) for minimum, normal, maximum and one additional flow condition. 1 watt is equal to 0.0013596216173039 cv. Cv for fluids cv for liquids is the volume of 68°f water in u.s.

Gallons/min d nominal valve size mm d internal diameter of piping mm d o equivalent circular flow passage diameter mm d h hydraulic diameter of a single flow passage mm f d valve style modifier dimensionless f f When sizing a control valve, the most common approach is to calculate the flow coefficient, cv which is a measure of the capacity of the valve body and trim. In deciding the size of the control valve that (port size) we need to calculate the cv value of the process (calculated cv) by calculating cv has educated more than 50 years, which is involved in. Gallons/min d nominal valve size mm d internal diameter of piping mm d o equivalent circular flow passage diameter mm d h hydraulic diameter of a single flow passage mm f d valve style modifier dimensionless f f Valves are tested by running water through it before publishing the cv value. The cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º f water with a pressure drop across the valve of 1 psi.

And determining flow through a valve can be simple. This technical bulletin shows how flow can be estimated well enough to select a valve size—easily, and without The units of cv (in the us) are usgpm/(psi 0.5). Engineering units are by default set to us units, but can be easily changed to si units. A valve cv can be described as the number of gallons per minute (gpm) at 60 o f (15.5 o c) that will pass through a valve with an associated pressure drop of 1 psi.
