      Check Valves

      CRP supply both the Atomac range of ball and check valves and manufacturer our own range of FluoroFlow spring assisted poppet check valves. The size range spans from ½”NB to 16”NB so we are likely to have a PFA lined check valve in our range to suit your requirement. We also offer combination sightglass / check valves for specialist applications. All valves in our range have PFA moulded linings for compatibility with the most corrosive and toxic chemicals and are all suitable for use up to 200 o C. Check valves have many uses within process lines, typically to maintain static head on pump discharges, prevent product batch contamination, provide simple nitrogen blanket control etc. We are confident we will have a valve suitable for your application.
