In the field of plant engineering key factors for the selection of equipment and components are weight, size and installation time. Functional range and performance are in turn very important criteria for process engineering. The GEMÜ 410 butterfly valve and its versions 417 and 423 meets stringent requirements in both respects. They are compact and lightweight, and can be installed quickly and easily. Furthermore, thanks to their wide range of functions, they are suitable for numerous applications in very diverse fields.

Space saving and easy to install

The butterfly valves in nominal sizes 15 – 50 - and up to 100 beginning in January 2012 - can be installed quickly and easily. They are easier to install than wafer and LUG type butterfly valves. In addition, the valve bodies of the butterfly valves come as standard with male threads. Therefore, no additional flanges, bolts, nuts and washers are required for installation in pipe systems. This simplifies installation and saves time and materials. Another advantage is compact installation length in all nominal sizes. This saves space and allows for cost-effective plant design.

Available with three operators

Depending on requirements, butterfly valves have pneumatic, manual or motorized operators custom-built for each specific application. The GEMÜ 410 butterfly valve is equipped with a low-maintenance, corrosion-resistant plastic pneumatic quarter turn actuator. Control functions "normally closed", "normally open" and "double acting" are available. The butterfly valve is optionally available with a stroke limiter and position indicator. GEMÜ 417 has an ergonomically designed manual operator with integrated locking device and intermediate stop in nominal sizes to DN 50. In DN 50 and larger the butterfly valve is fitted with a lockable hand lever which protects the butterfly valve against accidental operation. GEMÜ 423 has a low-maintenance motorized actuator with a powerful DC motor. The actuator features an optical position indicator and manual override as standard. The end positions can be adjusted electrically using microswitches.

Applications in nearly every industrial sector

All wetted parts of the soft-sealing butterfly valves are manufactured from high-grade plastic. They are corrosion resistant and are particularly well-suited for use in corrosive environments. To a certain extent, media may also contain solid matter. The potential applications of butterfly valves are highly diverse, from control and regulation of inert to corrosive media at medium temperatures between 10 and 60 degrees Celsius and pressures up to 6 bar.

The applications are wide-ranging. GEMÜ butterfly valves operate just as reliably in water treatment plants, swimming pool processes and irrigation systems as in the electroplating and chemical processing industries.
