There is an extensive array of valves from which to select for a process control operation. Each candidate valve is targeted by its designers for a range of fluid applications, fortified with construction materials and design features specifically suited for meeting the challenges of that application range.
Flowserve, under their
Valtek brand, developed a control valve that combines a number of useful design features. The MaxFlo 4 is an eccentric rotary plug valve intended for fluid control operations. The valve has some attractive design features.
- There is no shaft extending through the flow path, leaving flow unobstructed when the valve is fully open (see the illustration in the document included below).
- Valve trim provides tight bi-directional shutoff.
- Metal or soft seat construction is available to accommodate a wide range of applications.
- A variant provides flange to flange dimensions that allow the MaxFlo 4 to drop in as a replacement for standard size globe valves.
- High Cv rating may enable use of a smaller valve, when compared to other designs.
- Precise position control is delivered by the shaft form and plug mounting.
- Double offset eccentric plug eliminates sliding of plug across sealing surfaces, reducing wear and required seal maintenance.
More detailed information is provided in the document provided below. There is a revealing cutaway illustration showing the mounting and movement path of the plug. Share your industrial process control valve requirements and challenges with a
valve selection and automation specialist to get the best match of control valve to application.
