Siemens Building Technology 658-0052 Valve
The Siemens Building Technology 658-0052 Valve is a professional-grade 1/2 inch 3-way changeover valve engineered for precise fluid management in hydronic HVAC systems. Designed as part of the Siemens Powertop series, this valve features a 2.5 Cv flow coefficient and a quick opening flow characteristic, making it an ideal choice for 4-pipe radiant panel applications and terminal unit control. The 658-0052 is strictly a non-mixing changeover valve, configured with one inlet and two outlets to effectively direct the flow of hot or chilled water and ethylene glycol solutions (up to 50%) without cross-contamination. Its stainless steel stem and large diaphragm area ensure high control accuracy and a tight close-off rated for 250 PSI, providing the rugged durability required for commercial HVAC maintenance and building automation performance. This actuated valve assembly allows for seamless matched sequencing, ensuring stable temperatures and efficient system operation for contractors and facility engineers.
Key Benefits- Optimized Flow Control: The 2.5 Cv rating and equal percentage plug design provide superior controllability for radiant heating and cooling.
- Rugged Construction: Features a stainless steel stem and a brass valve body to resist corrosion and ensure long-term field reliability.
- Ease of Service: The removable actuator design allows for quick maintenance or replacement without disturbing the piping connections.
- Versatile Compatibility: Standard 1/2" NPT connections allow for straightforward integration into existing Siemens HVAC control architectures.
- High Close-Off Performance: Engineered with a large diaphragm area to maintain leakage-free shut-off even under high system pressures.
Is the Siemens 658-0052 suitable for steam applications?
Yes, this 3-way changeover valve is rated for low-pressure steam up to 15 psig, in addition to chilled water and hot water systems.
Does this valve allow for mixing of hot and cold water?
No, the 658-0052 is specifically a changeover valve designed to select between two outlets without mixing the media, which is critical for 4-pipe system integrity.
What type of actuators are compatible with the 658-0052?
This valve is designed for use with Siemens Powertop actuators, including the AG series for general close-off and the AH series for higher performance requirements.
