26 3 Way R Type Combination Diverter Model 45RK One inlet and two outlets R(right angle) design, Ram type Metal to metal sealing Dead space free Full bore unimpeded flow Stuffing box seal to atmosphere Fully jacketed

27 Replacing T pieces & Ball valves with Diverters Dead space area The clean alternative o Diverter valves seal at the take off point, eliminating dead space o Continuous back flushing is not required. o Design more compact T piece o Very advantageous, especially when 3 or more parallel outlets are required. Standby Valve Closed Ball Valve 2 Open The old solution o Normally T pieces and ball or plug valves are used to isolate the standby valve, resulting in dead space from the takeoff point o If the liquid is a solid containing slurry, the solids can settle in the ball valve and in the pipe. o One solution is the use back flushing, i.e. to continuously flush the dead lag back into the main line. However this adds cost and can considerably reduce plant throughput.

28 Four Way Diverter Valve Model 42 Five Way Diverter Valve Model 47

29 4 Way Diverter (Star design) Patented tangential star design Model 47DK One inlet and three outlets Outlets in one plane to inlet at right angles Star design, Ram type Metal to metal sealing Replaceable seats Dead space and slow space free Contoured, non rotating pistons unimpeded flow Stuffing box seal to atmosphere Completely jacketed

30 Pump Switching Diverter Valves 2 6 Way Feed Pump Diverter Valve o In many plants several pumps are used in parallel. Of these one is always in standby allowing for repair or maintenance without affecting plant performance. o Normally T pieces and ball or plug valves are used to isolate the standby valve, resulting in dead space from the takeoff point to the isolation valve. Diverter valves eliminate this dead space o Flushing / Cleaning / Draining valves can be included in the body of the diverter to optimise cleaning
