Introduction
The poly-jet flow control valves are a state-of-the-art engineering solution designed for the controlled modulation of water flows and the effective reduction of kinetic energy in pipelines. Engineered to convert static energy into cinematic energy by forcing flow streams to collide orthogonally in the center, these valves radically eliminate risks related to cavitation, severe vibrations, and noise pollution. Their exceptionally heavy and robust construction ensures the safe management of high-pressure discharges, fully protecting the structural integrity of the entire hydraulic network. Comprehensive details and dimensional variants are readily available for review within the downloadable catalog.
Key Features
Heavy-duty anti-vibration construction, advanced energy dissipation via orthogonal flow collision in the valve center, absolute structural immunity to cavitation erosion, high-sliding cylindrical mobile shutter, multi-orifice holed cylinder fully customizable with variable pitch, integrated hydraulic maneuvering jacks, adjustable limit switches, high-visibility position indicator devices, removable inspection plugs
