What are air valves?
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.
Air Valves perform two important functions in a piping system.
- They maintain system design efficiency, and
- 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 operations 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 will reduce the potential for destructive surges normally associated with uncontrolled air or a vacuum condition within the piping system.
Why are air valves important?
Air valves are vital accessories in an aquarium as they enable filters to function smoothly as well as aerate the water and make it easier for the goldfish to breathe. Additionally air valves play a crucial role in regulating the amount of air in the filters as well as the aquarium ensuring air is available only when needed and not in excess.
Constant supply and availability of fresh air is the source of life for any living organism and a goldfish needs exactly that to live a healthy and long life. Air valves can be fitted as a single valve, pairs of two, five or six that are well placed over the edge of the aquarium.
How many air valves do I need?
If you are new to keeping a goldfish, it is recommended that you use a three valve system where two boost the functioning of the filters while one expels excess air in the aquarium. These valves are very important as aeration problems can result from many causes. As an example, if the gravel is too fine, there is less air circulation thus debris collected at the bottom leads to pollution of the aquarium.
What happens if I don’t have air valves?
There is a possibility that food put in the aquarium, but not eaten by your goldfish will decompose. This in turn produces gases that are poisonous to the fish. This is when the air valves come in handy.
Air valves make the maintenance of an aquarium quite simple in addition to providing your fish a clean, healthy living environment.
Aquarium air valves and fittings come in different model varieties such as check valves, pipe valves, clamps and gang valves depending on what you find suitable for your type of aquarium.
How well you set up an aquarium for your goldfish determines how long they will live. Making sure that all required aquarium accessories are well fitted is the first step to ensuring proper functioning of your aquarium. Having a goldfish, is very appealing and with proper care your little swimmers can live for several decades without any major problems.
