Description
The Honeywell VCZAA1532 is a 1/2″ sweat (solder) connection, 2-way cartridge valve engineered with an equal percentage flow characteristic. Designed for hydronic heating and cooling systems, this cartridge-style valve delivers smooth, proportional flow control that makes it an ideal match for modulating actuators in zone valve applications.
Equal Percentage Flow Characteristic
The equal percentage characteristic means that equal increments of valve stem travel produce equal percentage changes in flow rate. This provides excellent controllability across a wide range of system loads, minimizing hunting and improving overall system stability — especially in variable-flow hydronic systems.
