What is the main feature of relief valves in a pump system?

The primary function of relief valves in a pump system is to relieve excessive pressure that may build up at the pump discharge. When the pressure exceeds a predetermined limit, the relief valve opens to allow some of the fluid to escape. This prevents damage to the equipment, as high pressure can lead to mechanical failures or unsafe conditions within the system. By ensuring that the pressure remains within safe operating limits, relief valves play a crucial role in maintaining the integrity and safety of pumping systems.

This feature is particularly important in preventing potential hazards associated with over-pressurization, which could result in leaks, burst pipes, or even catastrophic failure. Therefore, the main focus of a relief valve is centered around pressure management, which is vital for both operational efficiency and safety in pump systems.
