Apollo 61LF50201 3/8" FNPT Bronze Ball Cone Check Valve
Lead-free bronze inline ball cone check valve with 3/8" FNPT connections, 0.5 psi cracking pressure and 1.21 gpm flow
- Lead-free bronze body meets potable-water standards
- 5 psi cracking pressure opens with minimal flow
- 400 psi water rating handles high-pressure lines
- EPDM seals operate from 33 °F to 180 °F
- Stainless-steel spring resists corrosion for long service
3/8" FNPT Lead-Free Bronze Check Valve
The Apollo 61LF50201 is an inline ball-cone check valve with a bronze body and EPDM seals. It connects via 3/8 inch FNPT threads on both ends and is rated for water pressures up to 400 psi and steam pressures up to 15 psi WSP. Operating temperatures range from 33 to 180 degrees F.
Suitable for low-cracking-pressure water
This valve opens at 0.5 psi cracking pressure, making it suited to gravity-fed or low-head systems where minimal back-pressure is required. Installers needing a higher cracking pressure, a different connection type such as sweat or press-fit, or a valve rated above 400 psi water pressure should select another model.
0.5 psi cracking pressure governs installation
The 0.5 psi cracking pressure is the single figure that determines whether the valve will open reliably in a given system. If the available head pressure cannot exceed this value, the valve will remain closed and flow will be blocked.

Questions about this item
How do I install the Apollo 61LF50201 check valve and what orientation mistake should I avoid?
Thread the 3/8" FNPT ends into the piping using suitable sealant; the valve accepts horizontal or vertical mounting but flow must follow the arrow direction on the body.
Which component will need replacement first on the Apollo 61LF50201?
The EPDM seat and seal are the wear items; they degrade with thermal cycling and should be inspected during routine system maintenance.
What pressure limit will the Apollo 61LF50201 reach first under sustained high-pressure water service?
The 400 psi maximum water pressure rating is the primary limit; sustained operation near this value accelerates seat wear and spring fatigue.
