How should the relief valve discharge?

The relief valve should discharge by gravity. Relief valves are designed to open and release pressure in a system when it exceeds a specified limit, preventing potential damage or failure due to overpressure. Gravity discharge ensures that the expelled fluids can flow away from the equipment and are directed safely to a drain or designated area.

Utilizing gravity as the method for discharge is essential for the safe and efficient operation of mechanical systems. It ensures that the released materials do not accumulate and creates a passive discharge method that relies on the natural flow of gravity, thus minimizing the risk of backflow or blockage.

Other methods, such as pressure discharge or forced discharge, may introduce complexities or pressures that are not ideal for the safe operation of the system. Consequently, gravity discharge is not only effective but also aligns with best practices in maintaining safety and reliability in mechanical systems.
