The JOEPAI Stainless Steel Threaded 2-Way Ball Valve for Fire Protection is engineered to deliver unwavering reliability and superior performance in critical fire protection systems. Built with precision from high-grade stainless steel and featuring a robust two-piece design, this valve ensures a secure, long-lasting seal for on/off control in fire hydrant lines, sprinkler systems, and other water-based firefighting applications. Its highly visible red fire coating allows for quick identification during emergencies.
Our ball valve features a durable two-piece body design, bolted together for exceptional strength and service life. This construction provides a more compact and rigid structure compared to three-piece valves, minimizing potential leak paths. While offering excellent durability, the design also allows for relatively straightforward maintenance when required.
The valve is equipped with precision-cut threads, ensuring a tight, leak-proof connection to the piping system. This threaded end connection is ideal for permanent or semi-permanent installations where a robust and reliable joint is paramount. It simplifies installation in a wide range of systems without the need for special tools beyond standard pipe wrenches.
Manufactured from corrosion-resistant CF8 (SS304) or CF8M (SS316) stainless steel, this valve is built to withstand the test of time. It resists rust and degradation from moisture, aggressive atmospheres, and stagnant water commonly found in fire protection systems. This material choice guarantees the valve will operate flawlessly even after long periods of inactivity, ensuring system integrity when every second counts.
As a shut-off valve, its operation is simple yet highly effective. A quarter-turn (90 degrees) of the handle rotates a precision-machined ball with a through-bore. In the "open" position, the bore aligns with the pipe, offering minimal flow resistance and pressure drop. In the "closed" position, the solid side of the ball blocks the flow completely. In a fire protection system, this ensures that water flow can be instantly isolated to specific sections for maintenance or, in an emergency, to ensure full water pressure is directed to the active suppression lines.
This product falls under the category of Full-Port (Full-Bore) Ball Valves, meaning the bore diameter is approximately equal to the pipeline's inner diameter. This design is critical for fire protection as it minimizes pressure loss across the valve, ensuring maximum water volume and pressure reach the sprinklers or hydrants. It is specifically designed for On/Off Service and should not be used for throttling flow.
