Dual Plate Check Valve

The Dual Plate Check Valve is widely acceptd as the check valve of choice for new build energy, hydrocarbo and process projects by end- user and engineered contractor alike. The Goodwin Dual Plate Check Valve is used in standard, regular and bulk applications, where unwanted phenomena such as slam and waterhammer are not anticipated. Its available in different body styles to meet customer's specification.
Goodwin Dual Plate Check Valves are offered as a "retainerless" as standard in its wafer, flanged, hub-end and buttweld end body styles. Having no screwed body plugs, and unbroken pressure envelope, the Goodwin retainerless design provides:

  • Higher integrity pressure vessel than retainered design
  • Fugitive emission free design
  • No thread corrosion risk (as in "retainered" designs with screwed body plugs)
  • Tamperproof design
  • No plug blow out risk
  • Ease to disassembly
