Description
The Resideo SV173 SuperVent is a high-performance automatic air eliminator engineered to keep hydronic heating and cooling systems running at peak efficiency. Its high-capacity venting action continuously purges trapped air — the leading cause of system noise, reduced heat transfer, and energy loss — so your system delivers consistent, reliable comfort.
Built with a durable brass body and a 3/8″ NPT connection, the SV173 integrates seamlessly into standard residential and commercial hydronic systems. The built-in check valve is a standout feature, enabling fast, convenient servicing without the need to drain the system — saving time and reducing downtime on every maintenance call. Rated for working pressures up to 150 PSI and temperatures up to 240°F, this air vent is engineered to perform in demanding HVAC environments where dependable air removal is non-negotiable.
