We supply ASME B16.34-compliant 2-piece ball valves cast from ASTM A216 WCB (carbon steel) or ASTM A351 CF8/CF8M (stainless steel). Sizes range from DN8–DN100 (¼–4 in.), rated Class 150–400 LB, with PTFE packing for reliable sealing. Valves feature lever operation and threaded (NPT/BSP) ends, making them ideal for oil, gas, chemical and general industrial service where tight shut-off and easy maintenance are required.
