• Quiet operation
  • Zero maintenance
  • Design prevents backflow
  • Will seal around solids
  • Designed to withstand wear
  • Tough enough for abrasive slurries

The Series CPO Slip-On Check Valve is designed to be efficient, quiet and tough. It requires no external power sources, thereby reducing operation costs. The valve's simple design means there are no moving mechanical parts to break down or jam, reducing maintenance costs.

CPO Valves easily handle corrosive or abrasive materials such as raw sewage, sludges or slurries. Their flexible design allows solids to pass through unhindered and can even seal around solids trapped in the valve.

Series CPO Slip-On Check Valves are versatile and can be installed either horizontally or vertically. Drilling is available in all flange standards.

When placing your order, please indicate sleeve material by appending elastomer abbreviation (CR, NR, etc) to the model name. IE: Series CPO-CR
