NIBCO Fig No KT-291-W3 1/4 in Bronze Globe Valve, Side Outlet Threaded

Description

Product Overview

The NIBCO Fig No KT-291-W3 is a precision‑engineered bronze globe valve designed for demanding fire‑protection and industrial plumbing applications. With a 1/4 in side‑outlet connection, the valve offers a compact footprint while delivering a full 400 psi water working pressure, meeting the rigorous standards of NFPA fire‑suppression systems. Its robust bronze construction provides excellent corrosion resistance, ensuring a long service life even in harsh environments.

Key mechanical features include a screw‑in bonnet that simplifies installation and maintenance, an integral seat that guarantees a tight seal, and a renewable seat disc that can be replaced without removing the entire valve. The three‑way design enables precise flow control, making it suitable for both throttling and on‑off applications. The valve’s dimensions—2.25 × 1.75 × 1.75 in—and weight of 4.29 lb allow for easy integration into tight spaces without sacrificing performance.

Manufactured by NIBCO INC., a trusted name in fluid control solutions, this globe valve carries the legacy of over a century of engineering excellence. It is listed under the best‑selling #55 in the Globe Valves category on Amazon, reflecting its popularity among professionals who require reliable, high‑quality components for critical infrastructure.

Usage

Designed for fire‑protection systems, the KT‑291‑W3 excels in sprinkler installations, fire‑pump discharge lines, and fire‑hose connections where dependable flow regulation is essential. Its bronze body resists the corrosive effects of water treatment chemicals, making it a preferred choice for municipal water supplies and industrial cooling loops that demand consistent performance over many years.

Beyond fire safety, the valve is well‑suited for general industrial plumbing, including chemical processing plants, HVAC chillers, and water‑distribution networks. The side‑outlet configuration simplifies pipe routing, reducing the need for additional fittings and minimizing potential leak points. Engineers appreciate the valve’s ability to handle high‑pressure differentials while maintaining a smooth, laminar flow, which helps to reduce energy consumption and wear on downstream equipment.

Installation is straightforward thanks to the threaded connections and screw‑in bonnet, allowing technicians to secure the valve quickly without specialized tools. The renewable seat disc further reduces downtime, as maintenance crews can replace the sealing element on‑site, extending the valve’s operational lifespan and lowering total cost of ownership.
