How are actuated needle valves typically operated in industrial applications?

Actuated needle valves are automated needle valves that are typically operated by connecting them to hydraulic motors or air actuators. This allows for precise control of the valve opening, which is essential for many industrial applications. While larger manifold systems often rely on automated valves for efficiency, specialized gas filling operations frequently opt for manual regulation.

FloMaster® Actuated (Needle) Valves are pneumatically operated and designed for automated systems. This means that they are operated by air pressure. Pneumatic operation is characterized by low flow rates and a substantial pressure drop. This provides operators with the ability to finely throttle and regulate gas flow as needed.

What are some of the most common applications for needle valves?
Needle valves are used in a wide range of industrial gas and petrochemical processing applications, including:

  • Aerospace: Control the flow of gases in aircraft engines, fuel systems and other critical applications.
  • Chemical processing: Control the flow of gases and liquids in chemical processing plants, refineries and other industrial facilities.
  • Gas cylinder filling: Fill gas cylinders with high-pressure gases, such as oxygen, nitrogen and acetylene.
  • Petrochemical processing: Control the flow of gases and liquids in petrochemical plants, such as those that produce plastics and fertilizers.
  • Propane systems: Control the flow of propane gas in residential, commercial and industrial applications.
