LowFlow control valves are often used in a laboratory or pilot plant applications. Installations such as these frequently require valve trim changes in order to meet varying flow requirements for a given application. We understand the value in manufacturing a product designed with this flexibility in mind. That is why all LowFlow control valves offer a multitude of Cv’s and flow characteristics in every line size. In addition, every LowFlow control valve comes with our Quick Change trim design. This includes seats that thread into the valve body, as opposed to being machined into it. Plus, our free-floating plug uses a bayonet connection to the stem for simple “pop off, pop on” plug changes. Not only do our control valves require no special tools for trim changes, our bolted body design means you don’t even have to take the valve out of line for trim changes or maintenance.
