Campbell 4102E bronze foot valve for pump systems
The Campbell 4102E is a spring-loaded foot valve built for water supply lines that need reliable prime retention. Its lead-free bronze body and stainless steel strainer suit potable water installations in residential, agricultural and light commercial settings. The inline FNPT design fits directly into 1-1/4 inch threaded piping without adapters.
Cracking pressure .5 psi
The valve opens at a low .5 psi cracking pressure, so shallow-well or boosted systems can re-prime easily. It withstands up to 250 psi water pressure and operates between 35 and 180 degrees Fahrenheit. Steam service is not rated, so the valve must not be used on steam lines or in applications exceeding the stated temperature range.
Horizontal or vertical mounting simplifies
The valve body accepts both horizontal and vertical orientation, giving flexibility in tight pump houses or well pits. The stainless strainer resists debris but should be inspected periodically because a clogged screen is the most common cause of lost prime. Thread sealant on the FNPT connections prevents leaks that would otherwise break suction.

Questions about this item
What does the 250 psi water-pressure rating mean once the valve is installed in a real system?
It is the maximum steady water pressure the bronze body and spring can handle without leaking or deforming.
How does the FNPT connection affect what pipe or fittings can be used?
The female National Pipe Taper threads accept a matching 1-1/4 in male NPT nipple or adapter; the taper seal requires thread sealant or tape.
What orientation and clearance does the spring-loaded foot valve need to mount properly?
It can be installed horizontally or vertically; allow enough space for the 1-1/4 in FNPT body and the internal spring assembly to move freely.
