Description
The Schneider Electric (Erie) VM3212 is a high-quality modulating three-way zone valve body engineered for precise flow control in hydronic heating and cooling systems. Designed to work with compatible Erie actuators, this valve body delivers reliable, proportional flow regulation to meet the demanding requirements of commercial and residential HVAC applications.
Product Overview
The VM3212 features a 1/2″ sweat (solder) connection for straightforward copper pipe integration, a 2.0 Cv flow coefficient for accurate system balancing, and a three-way configuration that allows for mixing or diverting service. Its modulating design enables smooth, continuous flow adjustment rather than simple on/off operation, resulting in improved comfort, energy efficiency, and system longevity.
