By 1985, for example, roughly half of Keystone's revenues came from overseas sales. Keystone's international strategy was relatively simple. It also wanted to utilize Anderson, Greenwood's excess production capacity to manufacture Keystone's breakthrough "K-Lok" high-performance butterfly valve, which it had recently introduced. Created by mismanaged federal energy policies and flat oil prices, which resulted in a decline in the number of oil-producing companies from 30,000 in the early 1960s to just 13,000 by the early 1970s, the oil slowdown crushed valve demand by that industry. At the same time, Keystone absorbed a major producer of industrial valves that significantly augmented both Keystone's and Anderson, Greenwood's product lines. A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. In globe valves, the plug is connected to a stem which is operated by screw, Check valves are self-automated valves that allow the flow of gases and liquids to move one way, preventing any reverse or backward flow of material inside a pipeline. Indonesia. 77 An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds pre-set limits. Canada Works The valve is constructed from either plastic or metal. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.
