Efficient in Every Way

Designed for maximum efficiency in tight spaces, Belimo’s ZoneTight zone valve offering sets new design and performance standards for both pressure dependent and pressure independent zoning applications. Unlike short stroke globe valves, the self-cleaning ball helps minimise energy losses caused by clogging and eliminates overflow from pump pressure seat lift. In addition, high close-off capabilities ensure shut-off and allow for true equal percentage flow characteristics.

More than a Standard Zone Valve

Super Compact and Versatile

Unlike short stroke globe valves, the zone tight self-cleaning ball helps minimise 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.

Product Range

Flow Application Tool

The Flow Application Tool will quickly calculate your desired flow, and allows field adjustable l/s or l/min 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 to perform 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 to eliminate energy loss and improve plant performance
  • Self-cleaning ball valve technology to provide 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
