What is an Axial Flow in the Check Valve?

Axial flow in the check valve means the fluid or gas flowing parallel to the axis. It is an axial flow shuttle structure design, and the disc assembly with spring has cushioning and anti-vibration functions. When the medium flows downstream, it will push open the disc and the fluid through the body via axial flow channel circulation. And the spring here has a cushion effect to avoid the impact vibration between the disc and the body when a standard check valve opens. When the medium flows in the opposite direction, the disc closes very quickly, and the disc and the valve seat are tight-fitted to cut off the fluid from the reverse flow direction.

Why is Axial Check Valve Used?

When flow is reversed in a pipe, this can cause hydraulic shock waves to pass through (also known as water hammer). This can cause severe damage to equipment in the pipeline if measurements are not taken to prevent this. The introduction of the correct check valve, in a fully closed position during reverse flow can prevent this from occurring and causing severe issues at the site.

Valves that prevent water hammer and close rapidly without slamming are called non-slam check valves

How are Axial Flow Check Valves Used?

Axial check valves are specifically designed for fast-reversing systems where backflow is a constant concern. It is categorized as a non-slam check valve as the valve closes without slamming meaning no excess pressure spikes are created. Most axial flow check valves are spring-loaded, with a single low-mass disc, which facilitates fast, dynamic response to a reduction in flow. Due to having a single disc and spring when the disc is opening, the force is balanced resulting in an even flow.

Axial Check Valve Benefits

• Protect pumps and compressor equipment from damage caused by backflow / reverse flow
• The streamlined flow path through the valve body avoids turbulence and prevents erosion and vibration. Reduce downtime, maintenance costs, and loss of production due
• The venturi-shaped body allows for high-pressure recovery resulting in reduced pressure loss – the reduced operating cost of equipment will increase energy saving
• Very effective in preventing water hammer
• Eliminate chatter and reduce the possibility of sudden valve failure
• Smaller footprint than conventional check valves
• Flexibility to cope with variable flow conditions
• Interchangeability with most conventional swing check valves without expensive piping modification
