A customer in China recently purchased the 3 millionth Fisher Fieldvue digital valve controller says its maker, Emerson. The company plans to use the water treatment pressure control valve in its membrane plant.

A digital valve controller helps regulate and monitor the opening and closing of a control valve. Emerson notes it provides information with respect to valve status and health. The company cites a herbicide plant in Iowa that reduced annual maintenance costs by $230,000 by using Fieldvue digital valve controllers to transition the facility from reactive to predictive maintenance.
