English term or phrase: valve points
Есть ли какой-то устоявшийся термин?

То, что это погрешности, вызываемые немоментальностью срабатывания клапанных систем – это понятно.

Контекст:

1) In the case of thermal units, the forbidden zones may be due to valve points.

2) These control response functions contain tunable parameters to account for nonlinear unit operating characteristics such as those caused by valve points.

3) These trajectories are economic allocations of the area controlled generation forecast that recognize the unit control modes, operating limits, response rate limits, valve point, emission constraints and network security constraints that are in effect for the forecast period.

D2. Valve point loadings cost
In the thermal units with multi-valve steam turbines, when steam admission valves are first opened, a sudden increase in losses is registered which results in ripples in the cost function (Fig.7). This effect is known as a valve point loading.

2.2. Valve Point Effect Loading
To model the cost function of generators in a more practical manner, valve point effect is considered where the input-output curve is not linear but consists of ripples as a result of the sharp increase in losses due to the wire drawing effects which occur as each steam admission valve starts to open.
