Key differences between the CGA 555 and the CGA 510:
Why the CGA 555 and not the CGA 510?
The answer is simple; the CGA 510 valve is the same fitting used in vapor gas applications such as barbecue grills, gas stoves and outdoor gas heaters. Well known valve manufacturers such as Rotarex, Rego, Sherwood and Marshall Excelsior do not, and will not allow their CGA 510 valve to be modified with a liquid withdrawal tube because this retrofit could lead to a very dangerous scenario when connected to other applications.
The CGA 555 valve features include:
- Excess flow ball limits flow in case of line breaks or accidental disconnects
- Fixed level vent valve
- Full length liquid withdrawal tube
- Pressure relief valve
