Manual Multi-level Hard Sealed Butterfly Valve

This manual multi-level hard sealed butterfly valve adopts flange connection, and the valve and pipeline flange are tightly fixed by bolts to ensure the stability and sealing of the connection; its core hard sealing structure adopts metal-to-metal sealing, relying on the precision-machined sealing surfaces to fit each other to achieve effective fluid cutoff and precise flow control. When working, the butterfly plate rotates 90° around the valve stem axis. When the butterfly plate is parallel to the pipeline axis, the valve is fully open and the medium passes smoothly; when the butterfly plate rotates to be perpendicular to the pipeline axis, the valve is closed to prevent the flow of the medium.

Our Shengshi Huagong manual multi-layer hard-sealed butterfly valve has become a key equipment in the field of industrial fluid control with its reliable performance and wide applicability.
