1/4" FNPT Bronze Check Valve

Apollo Valves 61LF10101 is a lead-free bronze inline ball cone check valve designed for 1/4 inch FNPT connections. It prevents backflow in water and steam lines with a low cracking pressure of .5 psi. The valve body uses bronze with an EPDM seal and RPTFE seat for chemical compatibility. Stainless steel spring ensures reliable closure across mounting orientations.

For plumbing systems needing low-head backflow

This valve suits installers working with potable water or low-pressure steam up to 125 psi where a compact bronze body fits. It operates between 33 and 180 degrees F at pressures up to 400 psi water. Buyers who need higher flow capacity than .85 gpm or larger pipe sizes should look at other models. The Prop 65 listing means it is restricted for some applications in California.

Cracking pressure .5 psi governs opening sensitivity

The .5 psi cracking pressure determines the minimum upstream pressure required to unseat the ball cone and allow flow. Systems with very low differential pressure rely on this figure to avoid unwanted restriction. Verify that your circuit can develop at least .5 psi before specifying this valve.

Questions about this item

How loud is the 61LF10101 when water runs through it all day?

The valve has no moving parts that generate noise; flow noise depends on your plumbing layout and pump, not on the valve itself.

What pipe fittings must I already have to install the 1/4" FNPT connections?

You need male NPT threads on both pipe ends — one for the inlet and one for the outlet — plus thread sealant rated for potable water.

Will the 0.85 gpm flow rating restrict the older 1/2" supply lines I plan to keep?

The valve is sized for 1/4" piping; if your existing lines are larger you must reduce them at the valve, which will limit flow to the rated 0.85 gpm.
