Gas Cylinder Valve Connector
Gas cylinder valve fittings come in a variety of standards and sizes, depending on the country’s developed standards or the type of gas being used. The existence of multiple standards is for safety reasons, preventing the incorrect connection or use of the wrong type of gas cylinder valve, which could be dangerous (Safety interchangeability).
The materials used to manufacture gas cylinder valve fittings are mostly metals that can withstand high pressure or corrosion well, such as brass and stainless steel. The choice of material depends on the type of gas and other application requirements, such as high-purity gas or corrosive gas.
Gas Cylinder Valve Connector standards:
The internationally recognized valve and fitting standards that are widely used worldwide and in Thailand include:
- The CGA (Compressed Gas Association) is a standard from the United States and is also commonly used in Thailand.
- BS (British Standard) is a standard from the United Kingdom.
- DIN (Deutsches Institut für Normung) is a standard from Germany and is widely used in Europe.
- JIS (Japanese Industrial Standards) is a standard from Japan, commonly used for automobiles and machinery from Japan.
- ISO (ISO 5145) is an international standard and is beginning to be adopted to unify standards.
Before use, you should check with the gas supplier again about the standards for that type of gas cylinder valve connector to ensure correct usage.
Selecting and using gas cylinder valve connectors.:
When selecting and using gas cylinder valve fittings, in addition to ensuring compatibility with standards and valve sizes, there are other factors to consider, such as:
Materials used in fittings, such as brass and stainless steel, are used to prevent rust and resist corrosion from certain gases and chemicals.
They can withstand high pressure for safe use.
The type of thread connecting to the hose (flexible stainless hose) or pipe for application includes NPT, BSPT, BSPP, etc.
The surface of the fittings is smooth to reduce the accumulation of particles and contaminants in high-purity gas systems.
