Butterfly Valve Wafer Type with Worm Gear Actuator – DN800 (32")

This heavy-duty butterfly valve features a wafer-type body and worm gear actuator, designed for precise flow regulation and reliable shut-off in marine piping systems. The worm gear mechanism provides smooth, effortless manual operation, allowing for stepless adjustment of the disc position. An integrated position indicator on the gearbox enables clear visual confirmation of the opening angle. The valve is equipped with fully open and fully closed limit stop bolts to ensure accurate positioning and prevent over-travel.

With a nominal size of DN800 (32"), this valve is suitable for large-diameter applications such as ship ballast systems, cooling water lines, and industrial fluid pipelines. The wafer-style design facilitates easy installation between flanges, saving space and reducing weight. Constructed from high-grade materials, the valve offers excellent sealing performance and long service life under demanding marine conditions.
