Bronze Safety Relief Valve

The Apollo 1060520 is a bronze safety relief valve designed for heating systems. It features a 1-inch FNPT inlet and outlet with a factory set pressure of 100 psig. The valve operates within a pressure range of 15 to 160 psi and a temperature range of 0 to 250 degrees F. It provides a capacity rating of 3,500,000 BtuH.

Heating System Protection

This valve suits installations requiring ASME Section IV compliance for hot water heating boilers and similar equipment. It is not intended for steam service, potable water systems, or applications exceeding the stated pressure and temperature limits. Buyers needing a different factory set pressure or a larger connection size must select an alternative model.

Factory Set Pressure 100 psig

The factory set pressure of 100 psig is the critical specification that determines whether this valve matches the system design pressure. Verify the boiler or vessel maximum allowable working pressure before purchase. The valve includes a test lever for manual operation checks.

Questions about this item

How can I confirm the valve is operating correctly once it is installed?

After installation, watch the test lever during a normal heating cycle; it should lift and release steam or water when system pressure reaches the factory set point of 100 psig and reseat cleanly once pressure drops below that level.

What components come in the box and what must be purchased separately?

The package contains the bronze safety relief valve with an integrated test lever, brass disc, silicone seat and alloy-steel spring; pipe fittings, thread sealant and any required discharge piping are not included and must be sourced separately.

Which pressure setting should I select for my heating system?

The valve is factory set to 100 psig and is adjustable within the 15 to 160 psi range; choose the 100 psig setting if your boiler’s maximum allowable working pressure matches that value, otherwise adjust the spring to the pressure your system requires.
