When properly maintained, three-piece ball valves are the most durable option among these product variations. Three-piece ball valves are ideal for high-cycle, high-pressure applications that experience extensive wear and tear. Most notably, three-piece ball valves have the ability to disassemble components for cleaning or repair, sometimes with the valve body still in place. This means that wear-prone elastomeric components, such as seals, can be replaced or replaced based on changing system conditions or age. Three-piece ball valves are available in a variety of connection methods, including Female National Pipe Taper (FNPT), socket weld, and pipe socket weld. Mounting bolts that can be screwed directly into the mounting flange Reduces the possibility of the assembly nut being dropped or lost when installing or servicing the valve Two-piece pipe adapter that allows the flange to rotate independently of the pipe connector for easier alignment Quickly and accurately align the valve center section Self-wear compensating stem seal design ensures long-term leak-free service.
