Jacketed Ball Valves
Jacketed ball valves wrap the body in a steam or thermal-oil jacket so wax, asphalt, sulfur, polymer and other media that solidify on cooling stay fluid through the valve. The series specifies an unusually wide body list — carbon and stainless grades, LC1/LCC/LCB low-temperature steels, duplex and super duplex, nickel-molybdenum alloy and Alloy 20 — with SS304/SS316 balls, PTFE or RTFE seals and graphite packing. Design evidence covers API 608, API 6D, BS 5351 and ASME B16.34 with face-to-face per ASME B16.10 and API 6D, fire safety to API 607 and API 6A, and testing per API 598 and API 6D. The dimension table runs DN15 to DN200 in jacketed core-over-jacket pairs, where the jacket enlarges the face-to-face over the equivalent standard valve.
