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:

- 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
