Russian translation:м.б. коэффициент расхода?...
Explanation:
Есть такая фишка в разделе Сахалин (valve cv =
коэффициент расхода клапана). А может быть это и "значение коэффициента вязкости" (constant viscosity value)... т.е. нужно бы точную область. Мне ранее попадалось только как указание на рассчетный коэф. вязкости жидкой среды.

А нет, вовсе и не теплотворность...

\"...The kvs value is the quantity at stroke s = 100 % (valve fully open). Analogous to this, the flowrate coeficient cv is described in the American literature and defined as follows: the cv value (in US gal/min) is the flowrate of water at 60 °F which passes through at a pressure loss of 1 psi with the relevant stroke s...\"

коэффициент пропускной способности клапана


Explanation:
... в л/мин.
Он же - коэффициент потока

Скорость водного потока в USGPM при 60оF, который течет через полностью открытый клапан с разницей давлений в 1psi.
