Apollo 511 Series Safety Valve

The Apollo 511 series safety valve is a bronze pop-type relief valve designed for pressure protection in plumbing and industrial piping systems. It suits installers and maintenance teams who need a factory-set device rated for 200 psi service.

Pressure Range and Factory Setting

The valve operates across a pressure range of 15 to 300 psi and arrives factory set at 215 psi. This fixed setting means the opening pressure cannot be adjusted on site, so the system design must match the 215 psi trigger point exactly.

Bronze Body with Stainless Internals

The bronze body carries 316 stainless steel disc and spring components with a metal seat rated from -320 to 406 degrees F. A 3/4 inch MNPT inlet and 1-1/4 inch FNPT outlet dictate the pipe fittings required, while the included test lever allows manual verification without tools.

Questions about this item

Should I pick the 15 psi, 200 psi, or 300 psi setting for my system?

The valve is factory-set to 215 psi and adjustable from 15 to 300 psi; select the set pressure that matches your system's maximum allowable working pressure.

What does the 215 psi factory setting mean when the valve is installed?

The valve will begin to open at 215 psi to protect downstream equipment from over-pressure.

How does the 3/4 inch MNPT inlet and 1-1/4 inch FNPT outlet affect installation?

The male NPT inlet threads into a female fitting while the larger female NPT outlet accepts a male pipe or adapter for discharge piping.
