Waste water treatment is not a traditional market for Velan valves, but Steve Babensse of Quarter Turn Controls saw an opportunity and sold Velan ball valves for waste water service. During an upgrade program in early 1998, the Greater Vancouver Regional District Lulu Island Waste Treatment Plant in Richmond B.C. decided to use ball valves instead of plug valves due to their higher Cv and lower torque. They purchased eight 10-inch SB-150 and sixteen 6-inch SB-150 to be used for digester sludge circulation on waste digesters. The memory seal ball valves were automated with Bettis piston actuators and Go limit switches. The valves, one of which is shown here to the left, have been working flawlessly since their installation.
