1/2 inch S-401 Gate Valve

The Legend Valve 104-403 is a 1/2 inch S-401 brass gate valve designed for plumbing installations. It provides a straight-through flow path when fully open for residential or commercial water supply lines.

Brass construction and Proposition 65 notice

The brass body offers corrosion resistance for potable water applications. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and birth defects or other reproductive harm.

Full-port flow capacity and installation limits

The gate mechanism allows unrestricted flow when open and positive shut-off when closed. It is not suited for throttling service or frequent cycling, and buyers needing a quarter-turn ball valve should consider a different valve type.

Questions about this item

Will the brass gate valve stem packing need periodic replacement to prevent leaks?

The brass gate valve uses a packed stem design; over time the packing material can wear and allow seepage, so re-packing or tightening the packing nut may be required.

What limits continuous flow through the 1/2" S-401 gate valve during extended use?

The gate valve is designed for full open or full closed positions; leaving it partially open creates turbulent flow that erodes the gate and seat, which becomes the primary wear limit.

Does the brass body and gate assembly generate noticeable heat or noise when water runs all day?

Brass conducts heat efficiently, so the valve body will reach water temperature quickly, but the full-port design keeps flow noise low even during continuous operation.
