Industrial GP50A100 Pneumatic Valve Positioner

Industrial GP50A100 Pneumatic Valve Positioner from WTM Valves & Services is a fully mechanical pneumatic positioning device designed to provide precise actuator control in industrial process systems. Built on the ITT Conoflow GP50/P50 lineage, the GP50A100 is a side-mounted positioner that accepts a 3–15 psi pneumatic control signal and drives pneumatic actuators with quick-acting, repeatable response and high-capacity airflow. Its rugged, precision-machined control body supports reliable operation in demanding environments, and it can be paired with an optional I/P converter for enhanced compatibility with digital control loops. The GP50A100 is widely used in power generation, oil & gas, chemical processing, water treatment, and general industrial automation, with applications spanning steam systems, process flow regulation, refinery operations, turbine controls, boiler systems, and both nuclear and conventional plant configurations. As a common replacement for legacy GP50/P50 positioners, it aligns with industry standards and is compatible with pneumatic actuators and control systems that require stable, repeatable valve positioning relative to a control signal.
