Introduction
The multi-jet energy dissipation valves (VH4 type) are the ultimate hydraulic solution for neutralizing kinetic energy within high-pressure pipelines. Engineered to convert static energy into cinematic energy by forcing flow streams to collide orthogonally in the center of the device, these valves radically eliminate risks related to cavitation, severe vibrations, and noise pollution. Their exceptionally rigid and robust construction ensures safe, reliable long-term control while fully protecting the structural integrity of the piping system. Complete design specifics and engineering charts can be reviewed in the downloadable catalog.
Key Features
Heavy-duty anti-vibration construction, advanced energy dissipation via orthogonal flow collision in the valve center, total elimination of cavitation damage on surrounding metallic walls, high-sliding cylindrical mobile shutter, integrated hydraulic maneuvering jacks, customizable holed cylinder based on specific flow rates, built-in inspection holes, adjustable limit switches, high-visibility position indicator devices
