Jamesbury PMV-Positioner Butterfly Valve Positioner

The Jamesbury PMV-Positioner is a valve-positioning accessory designed for Jamesbury 8-inch butterfly valves that are actuated by a pneumatic air actuator. By translating a control request into measured actuator movement, it provides more precise, repeatable valve travel and closer alignment between commanded and actual opening, improving flow control in process environments. The PMV-Positioner is intended to integrate with Jamesbury butterfly valve hardware, matching the 8-inch valve size and pneumatic actuator configuration to support reliable performance in automated systems. As part of the Jamesbury valve family, this positioner serves as the interface between process control signals and pneumatic actuation, helping ensure consistent valve positioning in industrial applications where dependable valve operation matters. In typical instrumentation setups, such a positioner enables smoother control of valve movement within pneumatic actuation systems, aligning with Jamesbury's engineering approach to durable, purpose-built valve accessories.
