Campbell 1" FNPT brass spring foot valve

This Campbell FV-4TLF foot valve suits pump systems that need a reliable check valve with an integral strainer. It installs inline on 1 inch FNPT connections and works in both horizontal and vertical orientations. The low-lead brass body and stainless steel strainer resist corrosion in potable water applications.

Sustained pressure and temperature performance

The valve handles continuous water pressure up to 200 psi and operates between 35 and 158 degrees Fahrenheit. A light 0.5 psi cracking pressure keeps the spring-loaded poppet seated until flow begins. Steam service is not rated, so the valve should only be used in liquid systems.

Installation notes and common issues

FNPT threads require proper pipe sealant and careful tightening to avoid leaks at the connections. Debris larger than the strainer openings can restrict flow, so the screen should be inspected periodically. The valve has no steam rating and must not be installed in steam lines.

Questions about this item

Does the 0.5 psi cracking pressure cause any water hammer or noise when the pump cycles on and off?

The spring-loaded design with a 0.5 psi cracking pressure provides a soft, controlled opening that minimises water hammer and keeps operation quiet during repeated pump cycles.

What piping and thread sealant do I need to install this 1-inch FNPT valve?

You need 1-inch NPT male-threaded pipe or fittings on both ends and a thread sealant approved for potable water to make the FNPT connections watertight.

Will the 200 psi pressure rating and 158 °F temperature limit work with my older cast-iron shallow-well pump?

Yes, the 200 psi water-pressure rating and 158 °F maximum temperature exceed the typical output of older cast-iron shallow-well pumps, so the valve will handle the pressure and heat without issue.
