1/2" FNPT Bronze Check Valve

The Apollo 6110301 is a 1/2 in inline Ball Cone spring check valve built for general purpose and steam service. It suits installers who need reliable backflow prevention in plumbing or low-pressure steam lines. The cast bronze body and RPTFE internals handle a range of fluids. It is factory tested before shipment.

Bronze body with RPTFE seat

The valve uses a cast bronze body with female NPT threads on both ends for inline piping. A spring-actuated ball cone mechanism opens at .5 psi and provides chemical and corrosion resistance through its RPTFE ball cone and seat. The design allows straight-through flow and accepts horizontal or vertical mounting with upward flow.

Check pressure and temperature limits

Verify that your system pressure stays within 400 psi non-shock CWP at 100 degrees F or 125 psi steam working pressure at 350 degrees F. Confirm the media temperature remains between 33 and 406 degrees F. Ensure the 1/2 in FNPT thread size matches your existing piping and that the Cv 1.4 flow coefficient meets your flow requirements.

Questions about this item

What does the 0.5 psi cracking pressure mean for the 1/2" FNPT check valve?

The valve begins to open when upstream pressure exceeds 0.5 psi, allowing flow in the forward direction while the spring keeps it closed below that threshold.

What pipe threads are required to install the 6110301 valve?

Both ends use 1/2 inch female NPT threads, so you need matching male NPT pipe or fittings for a direct inline connection.

Can the valve be mounted vertically and which way must flow go?

Yes, it can be installed vertically, but flow must travel upward so the spring can close the ball cone against reverse flow.
