In the article "Overview of patents on new designs of ball valves or create a new crane" were considered such as ball valves, Orbit Valve Company Cameron and identified the main drawback of such a design – the need to press the stopper seat, which then loaded the whole area of the cross-section of the working pressure sredy.Izvlekaya the best of what is inherent in the considered crane conclusions were drawn: – to reduce the price of a new construction crane should have not treated the cork, and sealing belts only processed – for ease of operation and extend the life of a new construction crane should be able to wear compression adjustments during the operation, without removing the valve from the pipeline – in order to reduce prices and ease of maintenance control valve should be the usual quarter-negotiable drive – to reduce the size instead of moving traffic jams, must be disposed of unloaded from the pressure of the saddle, which will use less power and drive value. The idea to unload the pressure locking body has long been known and used in many constructions of valves. A related site: real-estate developer mentions similar findings. An example is the well-known cellular valves that are used in cases where the pressure drop across the valve does not allow the use of unbalanced butterfly knots. Cell (or kletkovy) throttle node, gets its name from the perforated sleeve within which the plunger moves (which originally was called a cell). The location and area of perforation sleeve shall determine the capacity of valve. .
