GAF - Manual micrometric gas adjuster

Description

The GAF micrometric manual valve gas adjuster series is a line of manually operated regulation devices designed to precisely control the flow of gas and air in low‑pressure piping systems, commonly found in industrial combustion plants. These valves are engineered to provide accurate, stable and repeatable adjustment of flow rates, making them essential wherever fine modulation of combustion air or fuel gas is required.

Constructed with a durable cast‑iron body and equipped with a micrometric regulation screw, GAF valves allow operators to fine‑tune the flow by acting on an internal adjustment mechanism. They are available in both threaded and flanged versions, covering a wide range of sizes suitable for different system configurations. The series supports non‑aggressive gases as per standard classifications, hot air and flue gases, enabling flexible use across various industrial applications.

GAF valves are designed to operate within specific pressure and temperature limits, ensuring low leakage when in the closed position. It is important to note that these valves are not safety devices and are not intended for fuel shut‑off; their purpose is strictly flow regulation. For this reason, they must be installed within systems that comply with applicable safety standards and operated exclusively by qualified personnel.

Proper installation requires accurate alignment of the piping, correct use of gaskets and compliance with recommended tightening sequences and torque values. Routine maintenance involves checking gasket integrity, verifying bolt tightness, monitoring flow and pressure settings, and cleaning internal components to ensure optimal operation. Thanks to their mechanical precision, reliability and broad availability of configurations, GAF valves are a practical and versatile solution for controlling gas and air flow in industrial combustion environments.
