2-inch bronze gate valve for water lines

This Nibco S29 gate valve controls water flow in plumbing systems with a 2-inch nominal size. The bronze body and solid cast-brass wedge suit residential and light-commercial installations that require positive shut-off. Sweat connections on both female ends allow direct soldering to copper pipe. The non-rising stem keeps the handle height constant during operation.

EPDM seal rated for 200 psi water and steam

The EPDM seat seal handles operating pressures up to 200 psi for water and 200 psi for steam service. Bronze stem and screw-in bonnet maintain alignment under pressure cycles. Wheel handle provides mechanical advantage for smooth opening and closing without excessive force. Solid wedge design reduces turbulence when fully open.

Sweat ends need copper pipe and flux

Installation requires copper tubing, flux and solder to form permanent joints on both ends. The valve frees up system layout because the non-rising stem does not need overhead clearance for stem travel. Bronze construction resists dezincification in potable water applications. No flange bolts or gaskets are required for connection.

Questions about this item

How do I solder the 2 in sweat connections on the S29 gate valve without damaging the EPDM seals?

Remove the bonnet and wedge assembly before applying heat, keep the flame on the copper tube not the valve body, and use a wet rag to shield the bronze bonnet area while soldering both female sweat ends.

Which internal part of the S29 will wear first and need replacement during routine service?

The EPDM seal and cast brass wedge face are the primary wear items; inspect them whenever the system is drained and replace if the seating surface shows grooves or the seal has hardened.

At what pressure will the bronze bonnet threads on the S29 begin to leak under continuous 200 psi water service?

The screw-in bonnet is rated for the full 200 psi operating pressure; sustained use at that pressure will not cause the bonnet joint to leak unless the threads are damaged during installation.
