Ari-Astra Flow Regulating Valves

Ari Armaturen Ari-Astra Flow Regulating Valves: Enhancing Precision and Efficiency

The Ari-Astra Flow Regulating Valves are designed to provide precise flow control and efficient hydraulic balancing in various industrial systems, making them an ideal choice for applications where energy savings and operational accuracy are critical.

Key Features:

  • Precise Flow Regulation: The Ari-Astra valve utilises a combined flow regulating design, offering stepless control of volume flow. Its dynamic variants, such as the Ari-Astra Plus, provide automatic volume flow limitation using interchangeable flow control orifices and internal membranes. This system helps avoid over-supply issues, ensuring operational efficiency.

  • High Performance and Reliability: Constructed from materials like EN-JS1049 (spheroidal graphite iron), these valves are built for durability. They feature components such as a burnished X20Cr13+QT stem and seat rings made from the same high-grade material, providing excellent resistance to wear and tear. The double sealing system, including metal bellows and a safety stuffing box, ensures leak-proof performance, even under dynamic loads.

  • Energy Savings and Cost Efficiency: By limiting the volume flow independent of the differential pressure, Ari-Astra valves help optimise energy consumption. This results in significant cost savings over time, especially in retrofitting older systems. Maintenance is minimal due to their robust design and automated features.

Technical Specifications:

  • Sizes and Pressure Ratings: Available in nominal diameters ranging from DN15 to DN400, and with a nominal pressure rating of PN16, these valves can handle a wide range of system requirements.
  • Operating Conditions: Suitable for temperatures between -10°C to +200°C, with flow speeds of up to 4 m/s for liquids. These valves are designed to handle pressures up to 16 bar, depending on the size.
  • Flow Characteristics: The Kv values (flow coefficients) vary by size, ensuring the valve can regulate flow precisely to match your system's needs. For example, a DN150 valve provides a Kv value of 320 m³/h at full handwheel rotation.

Applications:

Ari-Astra Flow Regulating Valves are perfect for use in heating and air conditioning systems, water circuits, and industrial fluid handling where hydraulic balancing and precise flow control are necessary. The valves are designed to maintain optimal performance even under varying operational conditions.
