What is PESO Approval for Cylinder Valves?

PESO Approval for Cylinder Valves is an official clearance granted by the Petroleum and Explosives Safety Organisation (PESO) on cylinder valves employed in compressed gas cylinders in India. This shows that the cylinders meet all the applicable rules for Gas Cylinder, as well as any other standard requirements.

Considering that the cylinder valves operate at very high pressures, the PESO tests the design, quality of materials used, pressure capacity, testing, manufacturing process, and standards that apply to the specific type of valves before issuing approval.

Upon successful verification, PESO grants permission for the manufacturer/Importer to manufacture/import/supply the specified cylinder valves.
