Belimo Expands Voltage Range of ZoneTight Zone Valves

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


The ZoneTight range has expanded to include additional line voltage electronic fail-safe actuator operation for pressure dependent QCV, pressure independent PIQCV, and a retrofit solution for zoning applications.


The CQKBUP and CQKXUP actuator series offer electronic fail-safe functionality, on/off control, AC 100…230 V universal power supply, and UL certification. The new additional actuator models include:

  • CQKBUP-RR (Normal Close / Fail Close (NC/FC))
  • CQKBUP-LL (Normal Open / Fail Open (NO/FO))
  • CQKXUP (Factory clip setting, cable option, NC/FC or NO/FO as ordered)

The ultra-compact QCV leads the way in Belimo’s new generation of room and zone solutions equipped with a space-saving 2way or 3-way ball valve.

The PIQCV combines a differential pressure regulator with a 2-way control valve to supply a specific flow for each degree of ball opening regardless of system pressure fluctuations performing the function of a balancing valve and control valve in one unit.

 The CQK actuator series combined with the UBLK retrofit kits are replacement solutions for existing failed actuators on TACO Zone Sentry® zone valves, Schneider Electric™ VBB ball valves, or TAC Erie™ VM zone valves. Restores service quickly without removing the valve, saving on installation and downtime while increasing performance and efficiency.
