Standard EN EN DE
Gas Cylinder Valves for Cylinder Test Pressures Up to 300 Bar - Valve Inlet and Outlet Connections
Also Known As:
The DIN 477 standard pertains to the cylinder valves of compressed, liquefied and dissolved gases. Its specifications target the inlet and outlet connections of cylinder valves that are capable of handling cylinder test pressures up to 300 bar, unless specifically stated otherwise. The standard is applicable to valves that comply with the DIN EN ISO 10297 for cylinder valves.
Furthermore, the DIN 477 includes the requirement of gauges for the tapered thread W 31,3 × 1/14, which is used for acetylene gases. The standard aims to ensure the valve's compatibility with specific gas types and to maintain its safety and performance even at high test pressures. Adhering to this standard is essential for the proper functioning of cylinder valves and for ensuring the safety of the people and environment surrounding gas cylinder operations.
