Design & Construction
The bronze body construction provides excellent resistance to corrosion in hydronic water systems, while the brass trim ensures tight shutoff and consistent performance over time. The equal percentage flow characteristic provides precise control at low flow rates, making this valve well-suited for variable flow hydronic systems where accurate temperature regulation is critical. The stem-up-closed (normally closed) fail-safe position ensures the valve closes upon loss of actuator signal or power, protecting downstream equipment.
Applications
- Commercial HVAC hydronic heating and cooling coil control
- Fan coil units and air handling units
- Terminal unit flow control
- Building automation and energy management systems
- Variable air volume (VAV) and variable flow hydronic systems
