The Marvair 50214 is a three-way modulating zone valve body engineered for precise hydronic and HVAC zoning applications. Featuring a 1/2″ sweat connection for reliable, leak-free copper pipe installation, this valve body delivers smooth, proportional flow control with a 4.0 Cv flow coefficient — ensuring consistent system performance across a wide range of load conditions.
Key Features
- Three-way valve configuration for diverting or mixing hydronic flow
- Modulating valve body for proportional, stepless flow control
- 1/2″ sweat (solder) end connections for secure copper pipe integration
- 4.0 Cv flow coefficient for optimal pressure drop and flow balance
- Compatible with Marvair modulating actuators for complete zone control assemblies
- Designed for use in hydronic heating, cooling, and zoning systems
Application
The Marvair 50214 valve body is ideal for commercial and residential hydronic systems where precise zone-by-zone temperature control is required. Its three-way design allows the valve to divert or mix water flow between supply, return, and bypass circuits, making it well-suited for fan coil units, air handling units, and terminal equipment. The modulating action enables integration with building automation systems and DDC controllers for energy-efficient, demand-based flow management.
