Efficient in Every Way

Belimo’s ZoneTight zone valve designed for maximum efficiency in tight spaces and sets new performance standards for both pressure dependent and pressure independent zoning applications. The QCV and PIQCV provide 95% less power consumption than conventional zone valves and easily connects to the actuator allowing operators and technicians to install valves quickly, easily, and without the use of tools, helping to simplify commissioning and reduces labor costs.

More than a Standard Zone Valve

Super Compact and Versatile

Unlike short stroke globe valves, the zone tight self-cleaning ball helps minimize energy losses caused by clogging and eliminates overflow from pump pressure seat lift. Also, high close-off capabilities ensure shut-off (0% A – AB leakage) and allow for true equal percentage flow characteristics. Belimo’s ZoneTight zone valves are designed for maximum efficiency in tight spaces

Flow Capacity Application Tool

TheFlow Capacity Application Tool will quickly calculate your desired flow, and allows field adjustable Cv or GPM on the actuator to meet your designs.

Consulting Engineers

Your analytical skillset makes you an invaluable asset to your clients. Your job is to design systems and operating sequences that meet energy codes to make facilities run more efficiently. You constantly find yourself solving job site performance issues when it could be spent looking for new and innovative ways to save energy and improve building performance. Belimo ZoneTight zone valves offer:

  • Pressure independent valve that functions as a balancing valve and control valve in one unit reducing installation and balancing cost
  • Pressure independent valve performs perfectly from start-up; if a facility adds a new circuit, the flow control of the existing circuit remains intact; no rebalancing is required
  • Zero leakage and high close-off pressure eliminates energy loss and improves plant performance
  • Self-cleaning ball valve technology provides superior clog resistance and maintains occupant comfort
  • Smallest pressure independent valve on the market
  • 95% less power consumption than conventional zone valves that helps achieve LEED certification
