What is an air valve?

Air valves are designed to intake and release gasses (de-aerate) from pipelines during filling, emptying and regular operating to protect the system and its components from air pockets, vacuums and pressure surges.

How do single orifice air valves prevent airlocks in pipelines?

Airlocks are caused when gas accumulates in pipeline high points and restrict or completely stop hydraulic flow. Single orifice air valves are installed at these high points to allow accumulated gases to escape and prevent an airlock from forming.

What are the common applications of single orifice air valves?

Single-orifice air valves are used in applications that require uninterrupted fluid flow or experience significant changes in pipeline elevation:

  • Water distribution networks
  • Irrigation systems
  • HVAC systems

How does the design of a single orifice air valve work?

Single orifice air valves are installed at pipeline high points where gasses accumulate due to having a lower density than fluids.

These valves have a single opening controlled by a float that rises and falls with liquid levels. As more gas accumulates the liquid level lowers the float and the vale face opens, allowing the trapped gasses to escape.

Air Valve Case Studies

Air Valves & Hydraulic Analysis for Pumping Efficiency

T-T Flow recently supplied air valves to one of Europe's largest paper manufacturers to be installed in a new waste pumping station.

Due to the length of the overhead pipes, our experts also completed hydraulic analysis prior to installation to ensure optimal air valve positioning for efficient hydraulic flow.
