The effect of valve closure speed on surge pressures

Control valves play a major role in controlling surge (water-hammer) pressures in most pumping and pipeline systems. This can vary from pump control valves which ensure gradual starting and stopping of pumps, to relief valves which relieve surge pressures out of a pipeline; surge anticipating valves do the same thing. ...<< more>>

Throttle - Wikipedia

A throttle is the mechanism by which fluid flow is managed by the constriction or obstruction.. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. ...<< more>>
