● The fluid confficient of vave is equal to the same length of the pipe.
● Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
● Fused hard nickel alloy, chromium carbide or tungsten carbide coated seat and ball designs for abrasive and high temperature service.
● Compact body design with minimum weight and elimination of potential leak path.
