This three-piece stainless steel ball valve with NPT threaded ends offers a reliable, durable, and versatile solution for shut-off and flow control. Its three-piece body design allows quick maintenance or replacement of internal components without removing the entire valve from the pipeline—minimizing downtime and extending service life.
The precision-machined stainless steel body, full-bore floating ball, and PTFE seats ensure a secure seal and smooth quarter-turn operation for efficient isolation. NPT threaded end connections provide secure, leak-free installation into piping systems. Built from corrosion-resistant stainless steel, this valve is suitable for water, air, oil, gas, and a wide range of industrial and commercial applications. The lever handle allows safe manual operation, with optional automation available for added flexibility.
