Crafting our valve stems begins with the careful selection of bar stock, including stainless steel, carbon steel, and alloy steel, to ensure longevity and resilience. After the raw casting process, we grind and machine the valve stems. For standard valve stem designs with bulk quantity orders, we apply Automatic Cylindrical Grinding. For special designs or large-sized valve stems, manual cylindrical grinding is employed to ensure precision and quality. This process highlights our commitment to quality, ensuring durable and reliable valve stems for diverse industries worldwide.
