Legend Valve 104-407NL Gate Valve

This 1-1/2 inch S-401 no-lead brass gate valve controls water flow in residential and commercial plumbing systems. It is designed for installers who need a reliable shut-off component that meets no-lead material requirements. The valve suits new construction and retrofit projects where lead-free compliance is mandated.

Thermal noise and power characteristics

As a mechanical plumbing fitting, this gate valve generates no operational noise and draws no electrical power. It does not produce heat during normal use because it contains no moving electrical parts or active components. System pressure and water temperature remain the only environmental factors affecting its performance.

Installation requirements and system integration

The valve connects to 1-1/2 inch piping using standard threaded fittings compatible with the S-401 pattern. No external power supply, control wiring or specialised tools beyond normal pipe wrenches are needed for installation. It frees up design flexibility by providing a full-port shut-off without electrical infrastructure. The product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

How do I install the 1-1/2" S-401 gate valve and what step is often missed?

Thread the valve onto clean male pipe threads using PTFE tape or pipe dope applied in the thread direction, then tighten with a wrench on the valve body flats only; the step often missed is avoiding excess force on the handwheel or stem which can damage the gate mechanism.

What maintenance will the no-lead brass gate valve need over time?

Operate the handwheel fully open and closed once or twice per year to prevent mineral build-up from seizing the gate; if the packing nut develops a slow weep, tighten it slightly with an adjustable wrench while the valve is under pressure.

What limit appears first when the valve sees sustained flow in a hot-water system?

The brass body and gate are rated for typical residential hot-water temperatures; the practical limit is the pressure-temperature curve of the 1-1/2" threaded connection, so verify system pressure stays within the valve's class rating before continuous high-temperature service.
