The site managers contacted Fisher® sales personnel in Brussels and surge-control experts from the Severe
Service group in Marshalltown, Iowa, USA. Together, the Fisher team specified new valves to meet the site's critical
performance parameters. Fisher supplied two replacement valves that retained the fast-stroking speed,
but featured characterized trim, minimal hysteresis,improved performance monitoring, and the ability to respond to small step changes.
