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, they are suitable for numerous applications in very diverse fields.
The butterfly valves in nominal sizes: 15, 50 and up to 100, which 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. Another advantage is compact installation length in all nominal sizes. This saves space and allows for cost-effective plant design.
The GEMÜ 410 butterfly valve is equipped with a low-maintenance, corrosion-resistant plastic pneumatic quarter turn actuator. 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.
