Abstract

The actuating mechanism is for a non-return valve in a feed water system, has a plunber movable lengthwise between the open and shut positions. Under normal flow conditions a number of forces act on the plunger holding it in an intermediate position. A balance passage connects an internal portion of the valve to a more remote part of the system, so as to generate a further force acting on the plunger so as to hold it open. There is a valve in this passage, to allow reduction of the extra force concerned, and thus move the plunger from the desired open position to the intermediate one.
