DN80 (3") Wafer Butterfly Valve with Worm Gear Actuator

This DN80 (3-inch) wafer type butterfly valve features a worm gear actuator for smooth and effortless manual operation. The worm gear mechanism provides precise, stepless regulation of the disc position, enabling accurate flow control in marine piping systems, industrial fluid lines, HVAC, and water supply applications. The valve body is fitted with fully open and fully closed limit stop bolts to ensure reliable and repeatable positioning.

A built-in position indicator on the gearbox allows visual confirmation of the disc opening angle. Operation is intuitive: turn the handwheel clockwise to close, counterclockwise to open. The compact wafer style design facilitates easy installation between flanges, saving space and reducing weight. Constructed with high-quality materials, this valve offers excellent sealing performance and long service life under demanding marine conditions.
