Difference b/w Safety and Relief Valves

Why don't you just google it yourself? If you're not going to learn about these valves as you should , at least learn how to find the info yourself....

Different words for the same thing.

The Relief Valve is meant for Liquid and Safety Valve meant for STEAM, GAS Etc.

DHAYANANDHAN.

Basic function of these two valves are same but different name has been given due to specific services of each. Safety valve keeps the system safe by releasing the extra pressure of the fluid to open atmosphere or to atmosphere through vent system, while relief valves keeps the system safe by releasing the extra pressure of the fluid to the console or vessel at low pressure and fluid is available for recycle. Both these valves are used for both gases and liquids.

Examples: Oil relief valves are used in lubrication system of rotary machines. Relief valve releases extra pressure of oil to L.O. consol.

Safety valve on steam drums releases extra pressure in atmosphere to keep system safe.
