Description
Howell Bunger Fixed Cone Valve: The Ideal Solution for High Discharge Capacities
The Howell Bunger Fixed Cone Valve is an ideal solution for bottom discharges and dams, designed to handle very high discharge capacities with precise regulation. This valve offers cavitation-free discharge in all adjustment positions thanks to its intense energy transformation through umbrella-shaped radiation resolution. Constructed from high-quality stainless steel, it ensures exceptional durability and resistance to vibrations. With its flanged connection, annular flow passage, and precise regulation by closing cylinder, this valve is perfectly suited for demanding applications requiring high performance and maximum reliability.
