Aquarium Accessories – Why Your Aquarium Needs Good Air Valves

Air valves make the maintenance of an aquarium quite simple as well as providing your fish with a clean, healthy living environment. They enhance the function of fish tank filters by regulating air flow and aerating wate.


Before we get to why you need air valves, we need to define exactly what they are. According to Wikipedia, ‘an Air Operated Valve is a type of power operated valve that uses air pressure against a piston or diaphragm to produce linear or circular movement to operate a valve.’

What do air valves do?

Air Valves perform 2 important functions in a piping system

  1. They maintain system design efficiency, and
  2. provide system protection.

Technically speaking …

What is system efficiency? System efficiency is maintained by venting air, via the valves, from the system that can restrict flow and increase pumping costs.

How does it provide system protection? By exhausting and admitting air through the air valves during system operations. The times of operation include start-up, shutdown and critical conditions. Critical conditions means times of power failures or line breaks. The exhausting and admitting of air during these times reduces the potential for destructive surges normally associated with uncontrolled air or a vacuum condition within the piping system.
