Regulating valve three generations of product division

From the beginning of the century to the seventies and eighties after the time, the control valve is still at the level of the first generation of products. Its features are: â‘  six or seventy-year-level single-seat valve, double seat valve, sleeve valve as the leading product; â‘¡ This generation of product features not complete, had to rely on expanding product variety, variants to adapt to different Occasions, resulting in a variety of specifications, the use of regulating valve, calculation, selection, calibration, maintenance, spare parts and other special requirements; â‘¢ poor reliability, the use of the problem; â‘£ very heavy. The second generation of products will be from the reliability, functionality, weight to get a breakthrough. Its features are: â‘  full-featured ultra-light valve instead of many poor reliability, function is not complete, but also very clumsy products, that is, to replace it with the first generation of leading products single seat valve, seat valve, sleeve valve, to become the second On behalf of leading products; â‘¡ electronic electric full-function ultra-light valve to gradually replace the traditional implementation of institutions due to poor reliability, had to use the "pneumatic valve + electric valve positioner + gas source," a combination of pneumatic products from the second generation The main use of the valve to electronic electric valve based, this generation is expected to 10 years (2000 ~ 2010). The third generation of products is intelligent. In the application of the features are: â‘  interface with the computer; â‘¡ more reliable reliability, further decline in failure rate; â‘¢ control valve varieties and the use of regulating valves to further simplify.
