The FISHER 6358 pilot controller is a high-performance pressure control device used in pilot-operated relief valves and backpressure regulators. Designed for precise pressure regulation, it provides stable and reliable control in gas and liquid systems.
This configured unit (6358-1K748527202-6358) is part of the Fisher 6358 Series, commonly installed on main valves such as EZR, 289P, and 1808 systems. It ensures accurate response to pressure changes, helping protect equipment from overpressure and maintain consistent system operation.
