Apollo 61LF10201 3/8" FNPT Check Valve
This Apollo 61LF10201 check valve uses an inline ball-cone mechanism inside a lead-free bronze body. It connects via 3/8 inch FNPT threads on both ends. The valve suits plumbing systems that need automatic backflow prevention in a compact fitting.
Pressure and temperature limits
The valve handles up to 400 psi water pressure and 125 psi steam pressure. Operating temperature ranges from 33 to 180 degrees F. Cracking pressure is .5 psi. EPDM seals and an RPTFE seat handle these conditions. Stainless steel spring returns the cone.
Flow rate decides fit
Rated flow is 1.21 gpm through the 3/8 inch ports. Systems demanding higher volume need a larger valve. Horizontal or vertical mounting works. California Proposition 65 warnings apply. Buyers needing greater capacity should select a different size.

Questions about this item
Which Apollo check valve has 3/8" FNPT connections and a 0.5 psi cracking pressure?
Model 61LF10201 is a lead-free bronze ball-cone check valve with 3/8" FNPT x FNPT ends, a 0.5 psi cracking pressure and an EPDM seat seal rated to 180 °F.
What does the 1.21 gpm flow rating mean when the valve is installed?
At the rated 1.21 gpm the inline ball-cone opens fully with minimal pressure drop, allowing hot or cold water up to 180 °F to pass in either horizontal or vertical pipe runs.
What limits does the FNPT threaded connection and 400 psi pressure rating impose?
The FNPT threads seal directly to 3/8" pipe without solder, while the bronze body and RPTFE seat handle up to 400 psi water or 125 psi steam within the 33 °F to 180 °F temperature range.
