Siemens Building Technology VXG44.32-16 Body

Precision-engineered for demanding hydronic environments, the Siemens VXG44.32-16 3-way mixing valve body is a 1 1/4-inch threaded seat valve designed for seamless integration into closed-circuit HVAC systems. Built with a robust bronze CC491K (Rg5) body, this unit supports a substantial 18.5 Cv (16 kvs) flow capacity, ensuring efficient temperature control in medium-sized heating and cooling applications. With a PN16 pressure rating and a 100:1 rangeability, it provides superior control accuracy for both mixing and diverting functions. The valve's linear characteristic in both the through-port and bypass ensures predictable performance across a broad medium temperature range of 1°C to 120°C. Designed for use with Siemens SAS.., SAT.., and SQS.. actuators, the VXG44.32-16 features high-grade CrNi steel internals and a 5.5mm stroke, making it a reliable choice for contractors managing chilled water or low-temperature hot water systems where leakage prevention is critical.

• Durable Construction: High-quality bronze valve body ensures long-term reliability in specialized HVACR applications.
• Precise Flow Control: Linear characteristics in both mixing and bypass ports facilitate smooth proportional control.
• High Tolerance: Rated for a maximum permissible operating pressure of 1600 kPa, suitable for varied circuit demands.
• Broad Compatibility: Optimally paired with Siemens Acvatix actuators like the SAS series for automated valve positioning.
• Low Leakage: Tight shut-off with a leakage rate of less than 0.02% of kvs ensures energy efficiency and system stability.

• Is the VXG44.32-16 suitable for open circuits? No, this 3-way mixing valve is strictly designed for closed circuits to prevent scale and mineral buildup.
• Can I use this body for both mixing and diverting? Yes, the VXG44.32-16 external thread valve is engineered for both mixing (port A/B to AB) and diverting (port AB to A/B) applications.
• What fittings are required for installation? This DN32 valve utilizes G 2" B connecting threads; we recommend using ALG323 brass or cast iron fitting sets for a flush seal.
