When to use bellows relief valve? Asked by: Dr. Mohammad Hansen MD Score: 4.5/5 (26 votes) Balanced bellows type valves are normally used where the relief valves are piped to a closed flare system and the back-pressure exceeds 10% of the set pressure, where conventional valves can't be used because back-pressure is too high.

Compensation for superimposed back pressure which is CONSTANT may be provided by reducing the set pressure of a conventional relief valve. A balanced bellows is recommended when built-up back pressure is expected to exceed 10% of set pressure. When superimposed back pressure is VARIABLE a balanced bellows is preferred.
