Round-flange rotary valve

Multijet Rotative Valves Nencini designs and produces multijet rotative valves. The simplicity of the design allows this valve to work under heavy flow condition for a long time. It is composed by one multi-hole plate assembled between two propeller-shaped plates, one fixed and the other rotating on the common axis. The valve control the flow operating in the full range between two end positions: ■ open when the blades of the two propellers are perfectly aligned ■ closed when the blades of the movable propeller overlap the empty room of the fixed propeller. The multi-hole plate provides a downstream flow in evenly distributed jets. Applications ■ water distribution systems ■ supply of reclaimed water for agricultural use and recharge of basins ■ headwork of water treatment plants ■ flow relief for pump, turbine by-pass and other hydroelectric utility applications ■ water intake at the bottom of dams and discharge control.
