Apollo 6210801 2" FNPT Stainless Check Valve

The Apollo 6210801 is a 2-inch FNPT stainless steel inline ball cone check valve designed for plumbing systems requiring reliable backflow prevention. It suits installers and maintenance teams working on water lines where a compact, corrosion-resistant valve is needed.

Inline FNPT connections integrate directly into

The valve connects via female NPT threads on both ends, allowing it to sit inline without extra fittings. Its horizontal or vertical mounting orientation gives flexibility in pipe routing, while the stainless steel body and EPDM seal handle water temperatures from 33 to 180 degrees F and pressures up to 400 psi.

Spring-assisted ball cone maintains seal under

A low cracking pressure of .5 psi lets flow start easily, yet the spring-loaded cone resists constant back-pressure without chatter. The metal-to-seat design with EPDM sealing sustains performance during prolonged pressurised operation rather than only brief surges.

Questions about this item

At what temperature does the 180 °F limit start to affect the valve?

The stainless steel body and EPDM seal are rated to 180 °F; sustained exposure above that can degrade the seal and reduce pressure capacity.

How much noise or heat does the 0.5 psi cracking pressure create during all-day flow?

The low 0.5 psi cracking pressure lets water move freely with minimal turbulence, so the valve adds no audible noise or measurable heat to the line.

What pipe threads must my plumbing already have for this 2 in FNPT valve to connect?

Your pipes need 2 inch female NPT threads on both sides; the valve screws directly onto them with no extra fittings.
