1/2" NPT Stainless Swing Check Valve

This 1/2 inch NPT swing check valve is built from 316 stainless steel for corrosion resistance in water and steam lines. It suits installers who need a reliable inline non-return valve for horizontal pipe runs.

Thermals noise and power draw

The valve operates passively with no electrical consumption or generated noise. It handles fluid temperatures from -4 °F up to 350 °F and withstands pressures up to 200 psi for water or steam service.

Build quality and daily implications

PTFE seals and a cracking pressure of .5 psi promote tight shut-off and low head loss at a rated flow of 6.9 gpm. Female NPT threads on both ends allow direct connection to standard pipe fittings without extra adapters.

Questions about this item

How do I install the 1/2" FNPT swing check valve so the disc seats properly?

Thread the valve onto 1/2" NPT pipe with the flow arrow pointing downstream; the horizontal mounting orientation means the hinge pin must sit level so gravity does not hold the disc open.

Which internal part will need replacement first and how often?

The PTFE seal on the 316 stainless steel disc is the wear item; inspect it whenever the line is opened and replace if the 0.5 psi cracking pressure no longer holds backflow.

At what temperature does the PTFE seal reach its limit during continuous hot-water service?

The valve is rated to 350 °F; sustained operation at or above that temperature will degrade the PTFE seal before the 316 stainless body shows any stress.
