Description
The Schneider Electric (Erie) VM3312 is a high-quality three-way modulating zone valve body engineered for precise hydronic flow control in commercial and residential heating and cooling systems. Designed to work seamlessly with compatible Erie actuators, this valve body delivers reliable, proportional flow regulation to meet the demands of modern building automation and HVAC zoning applications.
Key Features
- Three-way valve configuration for diverting or mixing hydronic flow
- 3/4″ sweat (solder) end connections for secure, leak-free installation
- 2.0 Cv flow coefficient for accurate, balanced hydronic system performance
- Modulating operation enables precise, stepless flow control
- Valve body only — pairs with Erie modulating actuators for a complete assembly
- Durable brass construction for long service life and corrosion resistance
- Ideal for fan coil units, air handling units, and hydronic zone control applications
Application
The VM3312 valve body is well-suited for hydronic heating and cooling systems where precise temperature control is required. The three-way design allows the valve to either mix two inlet flows into one outlet or divert one inlet flow between two outlets, providing flexibility in system design. Its modulating capability makes it compatible with DDC (Direct Digital Control) and building automation systems that require proportional control signals.
Installation Notes
- 3/4″ sweat connections require standard soldering techniques during installation
- Valve body must be paired with a compatible Erie modulating actuator (sold separately)
- Suitable for closed-loop hydronic heating and chilled water cooling systems
- Consult system design specifications to confirm Cv and pipe sizing requirements
