Rapid deceleration events or pump stoppages can cause column separation, leading to vacuum pockets and potential pipe collapse. An Air Release Valve functions as a bidirectional device that allows high-capacity air intake during sub-atmospheric conditions. This prevents vacuum formation and mitigates water hammer effects. By maintaining internal pressure balance, the Air Release Valve safeguards structural integrity in surge-prone systems, such as those in irrigation mains, transmission lines, and pumping stations.
When air is trapped near pump volutes, elbows, or control valves, it leads to localized vapor collapse and cavitation, accelerating internal surface damage. An Air Release Valve continuously removes microbubbles and larger air volumes that accumulate in high-turbulence zones. By doing so, the Air Release Valve reduces the risk of cavitation, minimizes pitting corrosion on metallic surfaces, and extends the operational life of both the valve and surrounding pipeline components.
Entrained air significantly affects flow meters by introducing compressibility errors and signal fluctuations, particularly in electromagnetic and ultrasonic systems. An Air Release Valve, strategically positioned upstream of metering assemblies, ensures a consistent, air-free fluid stream. This allows for precise volumetric measurements, improving billing accuracy and reducing calibration drift. The Air Release Valve is essential for high-accuracy measurement applications in water utilities, chemical dosing lines, and industrial batching systems.

Releases entrapped air at pipeline high points to maintain hydraulic gradient and prevent column separation during transient conditions.
Removes gas pockets in low-velocity zones to prevent flow restriction, vacuum conditions, and pipe deformation under surcharge loading.
Ensures air-free flow in high-pressure reverse osmosis systems to protect membranes and reduce differential pressure fluctuations.
Prevents air locking and emitter malfunction in long-distance drip and sprinkler systems with elevation variations and frequent on/off cycling.
Vents air during startup of condensate and feedwater lines to avoid cavitation and loss of heat transfer efficiency.
Removes entrained air to maintain accurate flow metering and prevent gas-induced corrosion in acid, alkali, or solvent transport lines.
Pumps operating in air-laden systems experience reduced efficiency due to increased head losses and turbulence. An Air Release Valve installed at discharge headers or pipeline peaks allows automatic venting of air, enabling pumps to operate at their best efficiency point (BEP). The reduction in air volume directly correlates with lower energy consumption, reduced NPSH issues, and longer pump bearing life.
High-pressure transients and rapid valve closures can expose air release points to extreme mechanical stress. An Air Release Valve with surge-resistant features, such as slow-closing floats or anti-slam devices, provides reliable operation even under fluctuating pressure conditions. Designed for systems with pressure ratings up to PN25 or ANSI Class 300, the Air Release Valve ensures no premature sealing or damage under dynamic load, making it suitable for power plants, desalination networks, and high-lift pumping systems.

Frigate air release valves are engineered with dynamic flow throttling features to manage sudden changes in internal pressure. The float mechanism is supported by damped motion control to avoid early closure under fast fill conditions. Anti-surge orifices reduce high-velocity air escape that could damage valve internals. This design protects the pipeline during pump trip, valve closure, or rapid draining events.
Frigate uses full-bore bodies and large-diameter orifices in its air release valves to handle solids without clogging. Internal surfaces are coated with abrasion-resistant and chemically stable materials like PTFE-lined stainless steel. The float and linkage system is isolated from flow paths to prevent jamming by debris. These features ensure reliable operation in sludge, effluent, or mixed-phase pipelines.
Frigate air release valves undergo finite element stress analysis to validate shell integrity under high pressure. Valve bodies are cast or machined from ductile iron, stainless steel, or super duplex alloys based on service pressure and media. All sealing interfaces are tested for leak tightness at 1.5x design pressure. This allows safe operation in booster stations, vertical risers, and transmission mains.
Yes, Frigate offers corrosion-resistant configurations using materials like Hastelloy, alloy 20, or titanium depending on the chemical profile. Non-metallic internal components such as PTFE or Viton seals provide chemical compatibility and temperature resistance. Selection is guided by fluid composition, temperature, and pressure to ensure long service life. These valves are used in desalination, chemical injection, and process plants.
Frigate calculates orifice size based on expected air discharge volume, system pressure, and pipe diameter. CFD simulations help optimize flow path and prevent sonic conditions during venting. For combination air valves, separate small and large orifices are used for continuous and surge air handling. Proper sizing ensures efficient air removal without allowing water escape or internal damage.
