Introduction
Ball hydro turbine safety valves represent the optimal engineering solution for the rapid and highly reliable flow interception in modern hydropower plants. Specifically engineered to withstand extreme high-pressure conditions, they guarantee a secure emergency closure to continuously protect critical turbines and penstocks. Their full-bore structural architecture aggressively minimizes hydraulic head losses, ensuring maximum operational efficiency and yield for the entire facility. Further configurations and precise dimensional charts are readily available for review within the downloadable catalog.
Key Features
Rapid and secure automatic emergency closure, bubble-tight mechanical sealing under extreme high pressure, extraordinarily low head loss when fully open, heavy-duty structural design tailored for severe hydropower applications, excellent resistance to continuous wear, highly reliable actuation even under critical emergency conditions
Technical Data Table
Applications and Benefits
- Water distribution networks and aqueducts: Extreme operational reliability featuring rapid flow shut-off and zero leakage;
- Complex industrial facilities: Complete safety ensured by built-in anti-static mechanisms and fire-safe backups that protect the infrastructure against fires and accidental overpressures;
- Engineering flexibility: Plentiful construction options, such as the extended stem, allow the valve to adapt perfectly to underground applications or insulated pipelines
