The fixed cone valve is a common valve, which is widely used. The fixed cone valve is driven by an actuator, mechanically, and has a welded steel body with a 60 Hastelloy gasket, a rubber sealing ring, and a 60 Hastelloy alloy. It consists of valve seat, guide vane and optional guide cover. So do you know what are the commonly used ranges of this fixed cone valve? 　 Fixed cone valves are commonly used in application environments such as dams, reservoirs, barrages or reservoirs. The fixed cone valve is also often used as a discharge valve in the side circuit of a hydro-generator set. It is also often used at the drainage outlet of the reservoir, the middle section of the water pipeline or the occasions where energy dissipation and drainage control is required. When the fluid flow is large, the flow velocity is fast, and the pressure is high, effective drainage and energy dissipation are imperative. 　 Fixed tapered valve tube, medium-sized tapered valve generally should be added
