3-piece full bore NPT-thread Ball Valve

The 3-piece full bore NPT ball valve is a versatile industrial valve designed for easy maintenance. Its three-piece body allows the center section to be removed for seal replacement without unscrewing the end caps from the pipe. The full bore design matches the pipe's inner diameter, ensuring maximum flow and zero pressure drop. Featuring NPT (National Pipe Thread) ends, it provides a secure, tapered seal for high-pressure water, oil, and gas applications.
