Applications

Four service conditions account for most of the positioners that leave this factory. Each page lists what the published specification actually supports — no project claims we cannot evidence.

Application

Oil, Gas and Refining

Control valves on hydrocarbon service are the classic case for a positioner: tight packing, high differential pressure and hazardous-area wiring rules.

Application

Power Generation and Steam Systems

Steam headers combine high temperature, vibration and valves large enough that the actuator needs help holding position.

Application

Chemical and Process Plants

Viscous, corrosive and solids-bearing media are where an unassisted actuator loses the valve position it was told to hold.

Application

Water, Wastewater and Utilities

Utility duty is high valve count, modest budget and a strong preference for one positioner family across linear and quarter-turn valves.
