The Double Regulating Balancing Valve (FODRV) is an essential component for achieving precision flow control and verification in heating or chilled water systems. Constructed from high-quality dezincification-resistant (DZR) brass, this valve features a fixed-orifice design that allows for accurate commissioning and system balancing.

  • Dual Regulation and Locking: Features a double regulating handwheel that allows you to preset the flow and lock the opening using an Allen key, ensuring the circuit can be isolated and reopened without losing the commissioned set point.
  • Durable Construction: The body and bonnet are manufactured from DZR brass, providing excellent resistance to corrosion in various water environments.
  • Integral Test Points: Equipped with built-in pressure test points before and after the fixed orifice for easy flow measurement and system diagnostics.
  • High Performance: Designed to operate within a temperature range of -10 °C to +120 °C with a maximum pressure rating of 25 bar.
  • Precision Accuracy: Engineered to maintain flow settings typically within ±5% of the set value for reliable system performance.

This compact balancing valve is the ideal solution for commercial and industrial HVAC applications where tamper-proof locking and highly accurate flow measurement are required.
