Explore our gallery showcasing onsite production photos of BOLA-TEK’s OEM valve balls and stems. From semi-finished valve balls—produced by bar stock, investment casting, forging, sand casting, centrifugal casting, or pipe—to fully machined balls in our ball machining shop, each image reflects our manufacturing precision. You'll also see raw valve stems from bar stock and finished stems crafted through automatic or manual cylindrical grinding, tailored to meet diverse industrial specifications.
