# kvs value

The Kvs value expresses the amount of flow in a regulating valve at a fully-open valve position and a pressure differential of 1 bar. The Kvs value is a special case of the Kv value, which indicates the flow at a given valve position and a pressure differential of 1 bar.

The K

_{vs}value expresses the amount of flow in a regulating valve at a fully-open valve position and a pressure differential of 1 bar. The K_{vs}value is a special case of the K_{v }value, which indicates the flow at a given valve position and a pressure differential of 1 bar.The flow at a lower pressure loss can be calculated by rearranging the equation:

K

_{vs}= Q / √ΔPwhere

K

_{vs}: K_{vs}value [m³/h]Q: Flow [m³/h]

ΔP: Pressure differential across a regulating valve [bar]
