Ball valves come in two basic designs: Floating Ball and Trunnion Mounted, with three basic construction variants: Single piece, Two piece, Three piece with End Entry and Top Entry with options of either full or reduced bore designs. Principally designed as an on/off isolation valve for a very wide range of temperatures and pressures they have inherent quick opening flow characteristics. Specially designed ball valves however, may offer good flow control capabilities at High Pressure. All ball valves offer compact actuation due to their rotary quarter-turn operation. Firesafe versions are available for use in the oil and petrochemical industries.
