Overview

The ZL47F-16 self-balancing valve automatically maintains a preset constant flow rate despite changes in differential pressure across the circuit, eliminating manual rebalancing in variable-flow systems. A spring-loaded cartridge modulates to keep flow steady, improving comfort and energy efficiency in heating and cooling distribution.
