The purpose of ball valves is to allow for easy control of liquids through pipes. They are used in many industries for a variety of applications, but are particularly common amongst home brewers.
Why a 2 Way Valve?
A 2 way valve may seem complex at first glance, but is fairly simple to use and install. Simply put, the handle allows the ball part of the valve to be turned to control the flow of liquid, allowing it to be turned on and off easily.
A stainless steel 2 way ball valve can, be cleaned using boiling water, which is essential for sanitization and longevity of the valve, and for better tasting beer. Lack of regular cleaning, even with stainless steel, can cause contamination which could result in an entire batch of beer needing to be discarded.
Why Stainless Steel?
Stainless steel is most commonly chosen by home brewers, and other professions, over other types of metal such as brass as it has the most useful features. The metal can handle much higher pressures and temperatures than others and corrodes less easily. It is even resistant to strong acids, which is what makes it ideal for a variety of heavy duty industries including oil and gas, catering, construction, and waste management.
Less corrosion in a home brewing kit means the beer will taste better and be free from contamination and the valve will last for longer before it needs to be replaced. This is also especially important for the food and beverage industry, or any application that involves consumables.
If you are still unsure whether or not a stainless steel 2 way ball valve is best for your usage, double check with a hardware expert or another home brewer. You will likely find that it is the perfect valve for you.
