What this gate valve does

The Nibco T29 is a bronze gate valve with female NPT threads on both ends, sized for 1-1/2 inch pipe. It is built for water systems where a straight-through shut-off is required and the valve can stay fully open or fully closed for long periods. The non-rising stem and wheel handle make it practical for tight spaces where a rising stem would hit surrounding structure.

Pressure and media limits

Rated at 200 psi for both water and steam, the valve suits typical residential and light-commercial plumbing pressures. The EPDM seal and brass seats handle hot water and low-pressure steam within that range, but the bronze body and cast brass wedge are not intended for aggressive chemicals, high-velocity abrasives or pressures above the stated maximum. The screw-in bonnet design means the pressure boundary relies on thread engagement rather than a bolted flange.

Installation notes

The female NPT connections require clean, properly cut male threads and a suitable sealant or tape to prevent leaks. Over-tightening can crack the bronze body or strip the threads, while under-tightening leaves a weep path. The non-rising stem means the handwheel position does not show gate position, so the installer must verify open or closed state by flow test after assembly. The wheel handle needs enough clearance to turn fully without striking adjacent pipes or walls.

Questions about this item

Which Nibco T29 gate valve size and connection should I select for a 1-1/2 inch female NPT line?

The T29 model listed here is the 1-1/2 inch version with female NPT threads on both ends, so it matches that pipe size and thread type directly.

What does the 200 psi rating mean when the valve is installed in a water system?

It indicates the maximum operating pressure the bronze body and EPDM seals are designed to handle continuously in water service without leaking or structural failure.

How does the non-rising stem and screw-in bonnet affect installation and operation?

The stem stays at a fixed height while the wheel turns, so the valve fits in tighter spaces, and the screw-in bonnet allows straightforward disassembly for seat or seal maintenance.
