Solid slurries and abrasive fluids pose a special challenge to valves. The unique multi-orifice design of Equilibar\u00ae valves lends itself well to slurry applications where there are solid particles suspended in liquid. Even in cases where the solids are hard enough to be abrasive and erode plastic or metal components, the simplicity of the Equilibar design allows our Engineers to tailor the valves to these aggressive conditions.<\/p> Contact Us to Learn More<\/a>

What are Common Challenges for Valves Dealing with Solid Slurries?<\/h3>

Clogging is a common concern. For all standard Equilibar back pressure regulators (BPRs) we advise filtration of 100 micron or higher. For processes where filtration is not possible, or solids larger than 100 micron are present, we do have some options. First, because Equilibar valves have a very wide operating range, we can oftentimes upsize the valve, moving to a larger GSD series valve<\/a> or the even larger BD series valves<\/a>. The larger orifices in these valves can be sufficient in preventing clogging unless the solids tend to clump together or agglomerate. If a standard design doesn\u2019t work, another option is to modify the design to further increase the internal flow path to minimize the chance of clogging.<\/p>

Abrasion or erosion of valve bodies and wetted parts is another concern when dealing with solid slurries. Depending on the hardness of the solids, the diaphragm or even the metal body of a valve can be eroded over time. Equilibar has many diaphragm options for valve design. For abrasive applications, our engineers have had success using thick rubber or polymer diaphragms (eg. thick Viton or PEEK) or more malleable metals like bronze. For the body of the valve itself, a variety of different alloys can be used; most commonly with difficult abrasive fluids, hardened 440C stainless steel has been used.<\/p>
