What are the set pressure and discharge pressure of a safety valve?
1 Answers
Safety valve set pressure, unless otherwise specified by the process, is 1.10 times the normal working pressure, with a minimum of 1.05 times. Function of safety valve: A safety valve is a protective valve whose opening and closing components remain normally closed under external forces. Discharge pressure: For steam safety valves, the discharge pressure should be less than or equal to 1.03 times the opening pressure; for air or other gases, it should be less than or equal to 1.10 times the opening pressure; for water or other liquids, it should be less than or equal to 1.20 times the opening pressure.
