"Modgal" Develops Revolutionary Control Valve to be Launched At Agritech 99.ROSH PINA, Israel--(BUSINESS WIRE)--Aug. 30, 1999-- Enables flow rates more than double those available with other valves; Quick response prevents pressure surge MODGAL will be launching, at the AGRITECH 99 exhibition (Haifa, Israel - September 5 - 9) a revolutionary control valve A device that modulates the flow of fluid in a conduit in response to a signal from a process measurement control system. developed by its subsidiary C-VALVES LTD LTD 1 Laron-type dwarfism 2 Leukotriene D 3 Long-term depression, see there 4. Long-term disability . The control valve, made of plastic, has the ability to convey fluids at flow rates more than double that of other valves of the same diameter. This new control valve has an extremely high-speed response (2-10 seconds, as compared with 8-100 seconds for other valves) which enables the prevention of pressure surges. A pressure surge is a phenomenon caused by a very quick increase in pressure, and it may result in a burst within the system. Therefore, it is crucial that C-valves be capable of preventing this phenomenon. The quick response of Modgal's C-valve is a result of years of research and innovative development. The valve has been designed to provide stable and accurate regulation in a very wide range of flow rates and pressure. It may be installed in systems in order to regulate flow rates ranging from no-flow conditions up to 450 cu.m/h (as compared with other valves with limited flow rate ranges). It has taken four years to complete the development of the new valve, during which it has undergone extensive testing, both within the laboratory and outside sites under actual working conditions. The development was supported by Israel's Office of the Chief Scientist Office of the Chief Scientist may refer to:

The valve lends itself to control by either a computer or by various fluids. It can be employed in a wide range of applications: -- Irrigation irrigation, in agriculture, artificial watering of the land. Although used chiefly in regions with annual rainfall of less than 20 in. (51 cm), it is also used in wetter areas to grow certain crops, e.g., rice. and agricultural water supply systems -- Municipal and local water supply and conveyance systems -- High-rise buildings and hotels -- Water treatment and effluent recycling systems -- Industrial processes MODGAL Ltd., is the leading Israeli manufacturer for products made of spheroidal spheroidal /sphe·roi·dal/ (sfer-oi´d'l) resembling a sphere. spheroidal resembling a sphere. , malleable malleable /mal·le·a·ble/ (mal´e-ah-b'l) susceptible of being beaten out into a thin plate. mal·le·a·ble adj. 1.
