Butterfly valve
Valves in which the opening and closing member (gate) is driven by the valve stem and moves up and down along the valve seat sealing surface
The opening and closing member (valve disc) is driven by the valve stem and moves along the axis of the valve seat (sealing surface) Valves that perform lifting and lowering movements. Valves that change the cross-sectional area of ​​the passage through the opening and closing parts (valve discs) to adjust the flow and pressure. Valves whose opening and closing parts (balls) rotate around an axis perpendicular to the passage. Valves whose opening and closing parts (butterfly plates) rotate around a fixed axis. Valves whose opening and closing parts (diaphragms) are driven by the valve stem to perform lifting and lowering movements along the axis of the valve stem and separate the action mechanism from the medium.
