Maxitrol recently introduced a new EXA Series. The E42, E52, E62 modulating valves are designed to have a linear relationship between the control signal and the flow rate. The flow rate is optimized over a 5:1 turndown. On atmospheric low‐pressure applications, the E42, E52, E62 Series has more consistent gain allowing the controller’s entire control signal range to be used and tuning is simplified.
The EXA Modulating Valves are a vast improvement over control valves using ball, butterfly, or poppet valves. The designs of other valves produce a parabolic flow rate characteristic that significantly reduces the effective control signal range of the controller and can make tuning difficult. The EXA Series also features a built‐in digital controller that provides a seamless interface with a process controller.
