Resideo by Honeywell SV175 1/2" NPT Supervent Automatic Air Vent

The Resideo by Honeywell SV175 Supervent is a high-quality automatic air vent designed to efficiently remove trapped air from hydronic heating and cooling systems. Featuring a 1/2" NPT threaded connection, this top-mounted air vent automatically releases air pockets that can cause noise, reduced efficiency, and uneven heating or cooling performance.

Key Features:

• Automatic air venting eliminates manual bleeding of radiators and baseboards
• 1/2" NPT male threaded connection for easy installation
• Top-mounted design allows air to naturally rise to the vent location
• Durable brass construction ensures long-lasting performance
• Float mechanism automatically opens to release air and closes when liquid is present
• Suitable for both heating and cooling hydronic systems
• Maximum working pressure: 150 PSI
• Operating temperature range: -20°F to 240°F

The SV175 Supervent is ideal for use in boiler systems, radiant heating applications, chilled water systems, and other closed-loop hydronic installations where air elimination is critical for optimal system performance. The automatic float valve design provides reliable, maintenance-free operation for years of trouble-free service.
