Types of relief devices are Conventional, Balance bellow & Pilot operated.

Question

Accepted Answer

Relief devices such as Conventional, Balance bellow, and Pilot operated are used in process engineering to protect equipment from overpressure.

Conventional relief devices are simple and rely on a spring-loaded mechanism to relieve pressure.
Balance bellow relief devices use a bellows to balance the pressure on both sides of the valve, allowing for accurate pressure relief.
Pilot operated relief devices use a pilot valve to control the opening and closing of the main relief valve, providing more precise pressure relief.
Examples include safety valves, pressure relief valves, and rupture discs.
