The flow control is achieved through the axial movement of a <strong>piston<\/strong>, operated by a rod and crank mechanism. The piston is positioned at the center of the valve body and moves within a specifically designed chamber to prevent <strong>noise <\/strong>and <strong>cavitation<\/strong>. This design ensures <strong>smooth <\/strong>operation <strong>without vibrations<\/strong>.   <\/p><p>The water flow is guided through an annular-shaped chamber around the streamlined central body. The section of this chamber continuously decreases from the inlet to the throttling point, enabling <strong>a smooth variation in flow and pressure<\/strong>. This geometrically optimized design confines cavitation bubbles to the center of the outlet, <strong>preventing valve damage<\/strong>.  <\/p><h3>Precision Regulation and Pressure Loss Minimization<\/h3><ul><li><strong>Ultra-precise flow control<\/strong> \u2013 Optimized design allows for highly sensitive adjustments, ensuring stable and progressive regulation.<\/li><li><strong>Reduced pressure losses<\/strong> \u2013 Hydrodynamic profile minimizes turbulence and optimizes flow efficiency.<\/li><li><strong>High resistance to cavitation and erosion<\/strong> \u2013 Ideal for high-velocity conditions and aggressive fluids.<\/li><li><strong>Plunger guidance system<\/strong> \u2013 Ensures smooth and seamless movement, reducing wear and extending the valve\u2019s lifespan.<\/li><\/ul><h3>Customizable Configurations and Accessories<\/h3><p>Flowrates annular valves are available with various options to meet the specific requirements of each application:<\/p><ul><li><strong>Available Actuators<\/strong> \u2013 Manual, electric, hydraulic, or pneumatic actuation for precise control and automation.<\/li><li><strong>Interchangeable Plungers <\/strong>\u2013 Different profile types available (conical, cylindrical, slotted) to fine-tune the flow regulation characteristics.<\/li><li><strong>Special Coatings and Treatments<\/strong> \u2013 Internal epoxy or Ebonite coating, resistant to chemicals and abrasion.<\/li><li><strong>Anti-Cavitation Design<\/strong> \u2013 Multi-orifice cavitation cage for progressive energy dissipation, minimizing cavitation effects.<\/li><li><strong>Check Valve Functionality<\/strong> \u2013 Can act as a check valve when standard check valve dimensions are insufficient, providing additional safety and reliability.<\/li><li><strong>Air Admission System<\/strong> \u2013 Dissipation plate and ventilation device to reduce cavitation impact on internal surfaces.<\/li><li><strong>Hydraulic Counterweight System<\/strong> \u2013 Allows the valve to function as a safety shut-off device for emergency applications.<\/li><\/ul><h3>Industrial Applications for Dams, Water Treatment, and Hydraulic Networks<\/h3><ul><li><strong>Water supply and distribution networks<\/strong> \u2013 Precise flow regulation for main pipelines and pumping stations.<\/li><li><strong>Wastewater treatment plants <\/strong>\u2013 Controlled flow management at inlet and outlet basins, optimizing treatment efficiency.<\/li><li><strong>Dams and hydropower plants<\/strong> \u2013 High-pressure water flow control, preventing cavitation and erosion.<\/li><li><strong>Aeration systems in wastewater treatment plants <\/strong>\u2013 Compressed air flow regulation in air intake networks, ensuring optimal oxygenation of biological basins and effective wastewater treatment.<\/li><\/ul><h3>Advantages of Flowrates Annular Control Valves<\/h3><ul><li><strong>Proven reliability<\/strong> \u2013 High-quality materials, robust design, and corrosion-resistant components.<\/li><li><strong>Precision and adaptability<\/strong> \u2013 Wide range of sizes, optimized plunger profiles, and customizable actuation options.<\/li><li><strong>Simplified maintenance<\/strong> \u2013 Easy replacement of internal components, reducing operational costs and maximizing system uptime.<\/li><\/ul><p>With their innovative design and advanced customization options, Flowrates annular valves are the ideal solution for industries requiring reliable, efficient, and long-lasting flow control.<\/p><h3 data-start=\"294\" data-end=\"357\"><strong data-start=\"294\" data-end=\"357\">Technical Features of the Flowrates Annular Control Valve<\/strong><\/h3><p><strong>Dimensions <\/strong>: 80 to 1800<\/p><p><strong>PN <\/strong>: PN10 \/ PN16 \/ PN25 \/ PN40<\/p><p>Flange dimensions according to EN 1092-2<\/p><p>High corrosion resistant materials.
