Fisher Controls 67AF Pressure Regulator

Fisher Controls 67AF Pressure Regulator is a pressure regulation device from Fisher Controls designed to maintain a defined downstream pressure in industrial fluid and gas systems. It works by modulating flow from the supply to the controlled line to compensate for changes in inlet pressure or downstream demand, keeping the setpoint steady. In process control environments, regulators such as the 67AF help protect downstream equipment from pressure fluctuations and support stable operation of gauges, sensors, and control valves. The model name identifies a specific regulator within the Fisher Controls product line, commonly used in instrumentation loops, process headers, and other points in a pipeline where reliable pressure control is essential. Because exact specifications for the 67AF are not provided here, consult official Fisher Controls documentation for the precise connection sizes, materials, pressure range, and mounting options relevant to your installation.
