They are an excellent option for water and wastewater treatment plants, aquatic and animal life support systems, chemical processing and handling, marine and corrosive environments, mining, metal plating and surface finishing, landfills and environmental infrastructure, and water parks and theme parks. The BYV series features reinforced lug holes and can be special ordered with overmolded 316 stainless steel lugs for dead-end service needs.
