Valve attributes: Choosing the Right Valve for the Right Water Application<\/strong><\/h1>\n

Have you ever installed a valve, only to have issues later because it was the wrong valve for the job?<\/p>\n

There are many options and several conditions that need to be considered when purchasing the right valve for the right application. It\u2019s important to understand the primary benefit of each valve design and the condition of the environment they are going to operate in. The goal is to choose the right valve to perform efficiently for its expected life, and at the most economical price. In terms of the water industry there are three areas that have different requirements.<\/p>\n

Wastewater<\/u><\/strong><\/p>\n

Valves used in wastewater conditions encounter solids, sludge (thick semisolid mixture), slurry (thin semiliquid mixture), and chemicals. These valves need to be resistant to clogs and leaks. Valves that are good for this kind of environment include Check Valves, Knife Gate Valve, Plug Valves, and Solid Wedge Gate Valves.<\/p>\n

Potable Water<\/u><\/strong><\/p>\n

Valves in contact with potable water need to be made from materials that are safe for human consumption, and resistant to corrosion. NSF 61 is the primary certification by the National Sanitation Foundation for contact with potable water and is required by the American Waterworks Association (AWWA) for water distribution valves. Choosing a reputable manufacturer that meets AWWA standards will help with quality assurance. Valves that are good for potable water include Butterfly Valves, Check Valves, Double Disc Gate Valves, Knife Gate Valve, Resilient Wedge Gate Valves – Rising or Non-Rising Stem, <\/a>Control Valves, and Solid Wedge Gate Valves.<\/p>\n

Fire Protection \u2013 UL\/FM approved Valves<\/u><\/strong><\/p>\n

Underwriters Laboratories (UL) listing and\/or Factory Mutual Research approval are often required for products used in fire protection systems.\u00a0 Valves used in fire protection need to handle high temperatures and pressures, while providing quick operation. These valves may not be used very often but need to be reliable on the occasion they are needed. Valves that perform well here include Check Valves, Control Valves, Post Indicating Butterfly Valve and Resilient Wedge Gate Valves – Rising Stem Valves (OS&Y) or Post Indicator Valves.<\/p>\n

Knowing the attributes of the different kinds of valves helps with selecting a suitable valve for the right environment and application. Here are key characteristics of the valves that are ideally suited for wastewater, potable water and fire protection.<\/p>\n
