Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for example: repair pack (2KE22Z0196-DC for DC voltages; 2KE22Z0197-AC for AC voltages)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OE22Z0196DCC 120/60)

Cv Flow Formulae

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.

The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.

Our sales department is ready to answer questions and to solve your valve needs. Please feel free to call, chat or email us.
