Belimo ZoneTight zone valves

Belimo ZoneTight zone valves are designed to work in small spaces. The QVC zone valves are suited for commercial buildings where higher close-off and the ability to change flow is desired. The self-cleaning ball valve technology resists clogs. The PIQCV zone valve combines a differential pressure regulator with a two-way control valve to supply a specific flow for each degree of ball opening. www.belimo.us
