Mô tả sản phẩm

Belimo ZoneTight™ Zone Valve

Designed specifically for installations with limited space, the Belimo ZoneTight™ valve combines innovative engineering with industry-leading performance for both pressure-dependent and pressure-independent HVAC applications.

The ZoneTight™ QCV represents the next generation of room and zone control solutions. Featuring a compact 2-way or 3-way ball valve design integrated with an electric actuator, the valve requires only 4.33 inches (110 mm) of installation height while delivering superior performance compared with conventional zone valves.

Key Benefits

  • Bubble-tight shut-off design eliminates energy losses caused by valve leakage.
  • Self-cleaning ball valve technology minimizes fouling and blockage.
  • Power consumption up to 95% lower than traditional zone valves.
  • Adjustable Cv settings provide flexible flow control to meet system design requirements.
  • Compact footprint simplifies installation in confined spaces.

Đặc tính thiết kế

Pressure Independent Quick Compact Valve (PIQCV)

The PIQCV combines all the advantages of a Pressure Independent Characterized Control Valve (PICCV) within an ultra-compact package.

By integrating a differential pressure regulator with a 2-way control valve, the PIQCV delivers a precisely controlled flow rate at every valve position, regardless of pressure fluctuations within the system.

The valve combines automatic balancing and modulating control functions in a single device, eliminating the need for separate balancing valves and improving overall HVAC system efficiency.

Technical Advantages

  • One of the most compact pressure-independent ball valve designs available on the market.
  • Ultra-low actuator power consumption of only 0.3 W.
  • Adjustable flow settings ensure accurate and permanent hydronic balancing.
  • Ideal for fan coil units (FCUs), chilled beams, VAV systems, and zone control applications.
  • Suitable for installation in restricted mechanical and ceiling spaces.
  • Eliminates the need for manual balancing during commissioning.
  • Maintains stable flow performance under varying differential pressure conditions.
