This company rounds off its proven series of Ecotrol control valves at the high end with the development of the nominal size DN 700 (28 in.). This valve has been specially optimized for use as an anti-surge valve on turbocompressors, but can also be used for all control applications involving liquid and gaseous media. The valve offers a high flow coefficient, K vs, which usually well exceeds the delivery capacity of the turbocompressor. The quantities of gas trapped inside the pipelines and heat exchangers can therefore also be relaxed in a very short space of time upon safety shutdown of the compressor. Actuating times are short — usually considerably less than 2 s for the complete 0 to 100% valve opening. — Arca Regler GmbH, Tönisvorst, Germany
