Apollo Valves CON-1061620 Bronze Safety Relief Valve

Product Description

The APOLLO VALVES CON-1061620 is a bronze safety relief valve with an oversized outlet, designed to protect closed hydronic heating systems from excess pressure buildup. The valve features a 1-1/4 inch FNPT inlet and a 1-1/2 inch FNPT outlet, providing an increased discharge area for reliable pressure relief. The body is cast from ASTM B584-C84400 bronze with a silicone seal, rated for continuous operating temperatures from 32 degrees F to 249.8 degrees F and a maximum operating pressure of 160 psi. Licensed plumbers and HVAC technicians install this valve as a critical safety component in residential and light commercial heating systems.

This valve is suited for closed-loop hydronic heating applications where an oversized outlet is specified to reduce back pressure on the discharge side. It is rated for heating service and is not rated for cooling, hot tap water, or solar heating applications. The 10 Series Safety Relief Valve line from Apollo is a commonly specified product in boiler and heating system installations requiring bronze construction and NPT connections. Each unit is packaged individually and manufactured in the United States in compliance with the Buy American Act.

Key Features

• Oversized outlet — 1-1/2 inch FNPT discharge versus 1-1/4 inch FNPT inlet — reduces back pressure during relief events
• ASTM B584-C84400 bronze housing for corrosion resistance in hydronic heating service
• Silicone sealing material suited for elevated operating temperatures
• Maximum operating pressure of 160 psi at 68 degrees F
• Continuous temperature range of 32 degrees F to 249.8 degrees F
• Compliant with Buy American Act (BAA) — manufactured in the United States

Compatibility

Designed as an OEM-style replacement or new-installation safety relief valve for closed-loop hydronic heating systems requiring bronze construction with 1-1/4 inch FNPT inlet and 1-1/2 inch FNPT outlet connections. Rated for heating service only; not suitable for cooling, hot tap water, or solar heating applications.

Installation Notes

Safety relief valves must be installed by a licensed plumber or qualified HVAC technician in accordance with local codes, ASME requirements, and applicable sections of the International Plumbing Code (IPC). Always shut down and depressurize the system before removing or installing a relief valve. The discharge outlet must be piped to a safe point of termination per code — never capped or plugged. Verify the valve set pressure matches the system design pressure before placing the system back in service.
