Siemens Building Technology VXG44.20-6.3 Body
The Siemens VXG44.20-6.3 is a high-performance 3-way mixing valve body engineered for precision control in closed-circuit hydronic systems. Featuring a 3/4" union connection and a 6.3 kvs (7.3 Cv) flow coefficient, this threaded valve is optimized for hot or chilled water applications where accurate temperature modulation is critical. Built with a robust bronze CC491K (Rg5) body and stainless steel internals, it resists dealloying and ensures long-term reliability in demanding HVAC environments. The linear flow characteristic in the bypass and equal-percentage characteristic in the through-port facilitate stable control loops when paired with Siemens SQS actuators. This externally threaded valve is designed for easy installation in mixing configurations, providing low leakage rates and high rangeability for commercial boiler loops and air handling units.
- Durable Construction: Bronze body and stainless steel trim prevent corrosion in hydronic circuits.
- Precise Modulation: 6.3 kvs rating delivers accurate flow control for localized heating and cooling zones.
- Standardized Compatibility: Seamlessly integrates with SQS series actuators for automated building management.
- High Temperature Range: Rated for medium temperatures from 1 to 120°C (34 to 248°F).
- Field Maintenance: Simple union connections allow for rapid installation and serviceability by technicians.
Common Questions:
What is the maximum pressure rating for the VXG44.20-6.3?
This valve body is rated for PN 16 (232 psi) static pressure, making it suitable for most multi-story commercial hydronic systems.
Can this valve be used for steam applications?
No, the VXG44 series is specifically designed for liquid water or water with antifreeze additives; steam will damage the internal seals.
Which actuators are compatible with this 3/4" union body?
This body is designed to work with Siemens SQS35, SQS65, and SQS85 electronic actuators using the standard 5.5 mm stroke.
