The 1 in. Brass Gate Valve, Female NPT, Full Port, Cross Handle is a full-port brass gate valve in female NPT × female NPT thread configuration. Gate valves use a multi-turn wedge mechanism to open or close the flow path — they are designed for infrequent, fully-open or fully-closed isolation duty in water mains, building supply lines, irrigation systems, and HVAC applications. Four-spoke cross handle provides excellent grip for infrequent operation in tight installations.

Key Features
- Full-port design — no turbulence or pressure drop when fully open
- Brass body and wedge resist corrosion in water, HVAC, and plumbing service
- Female NPT × Female NPT connections for direct pipe installation

- Do not use in partially open (throttled) position — causes gate vibration and seat damage
- Suitable for cold and hot water service up to 125 SWP
Gate Valve vs. Ball Valve
Gate valves are the traditional isolation valve for water mains and buried service — their multi-turn operation requires no space for a handle to swing 90°, and the straight-through bore causes zero flow restriction when fully open. Ball valves are preferred for frequent on/off operation. Gate valves excel in permanently-open isolation positions that are rarely actuated. See our Gate Valve vs. Ball Valve guide.
