Resideo SV173 Air Vent
When you're dealing with air binding in high-efficiency hydronic systems, the Resideo SV173 Air Vent provides the high venting capacity required to maintain optimal heat transfer. Designed as a 3/8" air vent with check vent, this unit integrates seamlessly with SuperVent PV Series products to eliminate the frequent need for manual bleeding. Built from heavy-duty brass, the SV173 automatic air vent is rated for a maximum operating pressure of 150 psi and can withstand temperatures up to 240°F, making it a reliable choice for both residential boiler loops and commercial radiant heating applications.
The internal debris baffle is a critical feature for technicians, as it effectively prevents dirt fouling and accidental leaking, reducing the risk of costly callbacks. For service work, the integral check valve is a major advantage, allowing you to replace the vent without draining the entire system or losing pressure. Whether you're troubleshooting hydronic air elimination issues or performing a fresh Resideo SV173 installation, this NPT-connected vent ensures quiet operation and long-term system integrity in any professional HVACR setup.
Key Benefits- Automatic Air Elimination: High-capacity venting reduces system noise and prevents air-related circulation failures.
- Service Check Valve: Allows for seamless maintenance and vent replacement without the need to drain hydronic systems.
- Industrial-Grade Construction: Corrosion-resistant brass body and high-temperature thermoplastic float ensure reliable HVAC air vent performance.
- Integrated Debris Baffle: Engineered to control dirt fouling, preventing valve clogs and unexpected leaks.
- Compact Profile: Measuring 2 inches in diameter and 3 inches high, it fits easily into tight mechanical rooms and manifolds.
How do I fix a leaking air vent on my boiler?
If a vent is leaking, it is often due to debris fouling the seat. The Resideo SV173 uses a built-in baffle to prevent this, but if a leak occurs, the 3/8" check valve allows you to unscrew the vent for cleaning or replacement without depressurizing the system.
Is the SV173 compatible with glycol-based systems?
Yes, the robust brass and thermoplastic internal components are designed to work effectively in standard hydronic heating and cooling systems, including those utilizing glycol additives for freeze protection.
Where should this air vent be installed for maximum efficiency?
For best results, install the SV173 at the highest point of the system or on top of a SuperVent air separator where air naturally collects, ensuring continuous air removal during operation.
