1 in Bronze Gate Valve

The Nibco S29 is a bronze gate valve designed for water supply lines that require full-flow shut-off. Its solder connection suits copper piping systems in residential and light-commercial plumbing. The non-rising stem keeps the overall height low where overhead space is limited. Installers who need a durable quarter-turn alternative should specify a ball valve instead.

Upgrade from worn stop valves

This gate valve replaces older globe or compression-stop valves that restrict flow and leak at the packing nut. The bronze body and silicon-bronze stem resist dezincification better than brass equivalents in aggressive water. The jump is worth it when the system sees continuous pressure up to 200 psi and temperatures up to 200 °F. It does not suit applications that need frequent throttling or rapid emergency closure.

Solder installation notes

Clean the copper tube ends and apply flux before sliding the valve into position; the 2 5/16 in lay length determines the cut length. Heat the joint evenly until solder flows into the cup, then wipe excess while warm. The hand-wheel handle operates the non-rising stem without changing valve height. Over-tightening the packing nut can crack the bronze bonnet and cause weeping.

Questions about this item

Will the 2-5/16 inch inlet-to-outlet length fit between my existing copper lines?

The valve measures 2-5/16 inches from inlet to outlet, so measure the gap between your pipes before cutting.

What is the correct way to sweat this 1-inch bronze valve without damaging the non-rising stem?

Remove the hand wheel and packing nut, wrap the body with a wet cloth, apply heat evenly to the solder cups, and avoid direct flame on the stem area.

How often should I replace the packing on the silicon bronze stem under 200 psi water pressure?

Inspect the packing annually; tighten the gland nut if seepage appears, and replace the packing material only when tightening no longer stops the leak.
