Campbell 3/4" FNPT Brass Check Valve

This Campbell check valve uses a 3/4 inch FNPT inline spring design with a low-lead brass body. It suits residential and light-commercial plumbing where back-flow prevention is required. The valve operates in horizontal or vertical mounting orientations.

Spring mechanism with NBR seal and stainless steel

The inline spring mechanism cracks at 0.5 psi and uses an NBR seal with a stainless steel spring and bronze seat. These materials handle water up to 200 psi and temperatures between 35 and 158 degrees F. The valve delivers a flow rate of 13 gpm and is not rated for steam service.

Straightforward threaded installation

Installation uses standard 3/4 inch FNPT threads on both ends. The valve mounts horizontally or vertically, reducing alignment issues. The main risk is debris preventing the spring from seating fully, so flush lines before fitting. Steam systems are not supported.
