Ball valves are widely used in fire water supply pipelines due to their excellent reliability and rapid shut-off capability, serving as crucial on/off valves. Their core design features a rotating ball with a bore through its center. A simple 90-degree (quarter-turn) operation of the handle allows for full opening or closing of the water flow, ensuring quick and effective water control during emergencies.
Joepai produced high-quality fire ball valves utilize precision-engineered sealing components to create a true watertight seal. This superior sealing performance remains effective over the long term, preventing internal and external leaks, and ensuring the fire water supply is always ready when needed.The unique quarter-turn design enables extremely fast and effortless opening and closing operations, which is critical in fire emergency response where every second counts.When fully open, the straight-through flow path through the ball's bore essentially matches the pipeline diameter, creating a near straight-pipe flow path with minimal resistance to fluid, helping to maintain the system's water pressure.Robust construction and high-quality materials allow ball valves to withstand the high-pressure conditions of fire protection systems, offering a long service life with simple routine maintenance.
Fire ball valves are available in a wide range of specifications, from DN15 (½ inch) to DN1200, to meet diverse requirements from indoor fire hydrants to large industrial fire main pipelines. It is important to note that the primary function of a ball valve is on/off and isolation, not precise flow regulation. Using it frequently for throttling applications can cause erosion damage to the valve seat due to high-velocity water flow, compromising its sealing integrity. Therefore, dedicated control valves are recommended for applications requiring precise flow control.
Our fire ball valves are strictly designed and tested in accordance with international standards, making them a reliable choice for ensuring the safety of fire protection systems in commercial buildings, industrial plants, and various critical facilities.
