The types of brass used for gas valves

Brass materials with varying percentages and characteristics of alloy elements are used in the design of gas valves.

For all industries involved in the hydraulic connections and valves and fittings sector, the choice of brass is very important and can vary depending on the intended operating conditions.
As it is an alloy that is made of copper and zinc and other alloys in smaller quantities, it is crucial to use the correct percentages to guarantee consistent results with the purpose for which the gas valves were designed for.  
For example, the greater the zinc content, the more mechanical resistance will increase, but this will also increase in the brittleness of the component.  The gas valves must guarantee correct closing of the valve to avoid any release of gas, which could constitute a danger for the site and any operators nearby. The alloy elements also have to be of the correct content to avoid structural failures.
Therefore zinc percentages should never be too low, but remain no more than 45 %, as any values above this limit will mean that the brass for the gas valves is no longer of engineering relevance.
Therefore the mix of such elements should obtain a type of brass with the right combination of zinc and other metals to provide the correct solution for each component category designed by Gnali Bocia.
