Valves Description: FIVE TIPS FOR SELECTING RIGHT Valves !Knowing what makes a valve the right choice-Valves control gas and liquid flow in almost every process and system. As common as they are, choosing the right valve can sometimes be time consuming and confusing.Begin valve selection by first gathering some basic information on system performance requirements. Knowing this will make it easier to find the right valve. The five tips in this article focus on how to match valve features with these requirements. Tip 1 – Valve size and type Choose the right valve type. Every valve needs to perform one or more basic functions:Shut off flowDivert flowMix flowPressure reliefBackflow preventionAdjust flowFunction determines the design of standard valve types.Properly sizing the valve is also important. The right valve choice means matching the valve’s size to expected flow through the system.Tip 2 – Materials of constructionKnow the chemical compatibility requirements. The valve materials need to be compatible with the gases or liquids flowing through it. Plastic valves usually resist harsh or corrosive chemicals better than metal valves.Tip 3 – Performance requirementsDetermine the pressure and temperature requirements. Find out both the temperature and pressure ranges where the valve will be installed. Metal valves tend to withstand higher temperatures and pressures than plastic valves. Metal valves are also usually best for pressurized gases. This is because they tend to be stronger than plastic va... View Full Blog Content...
