Internal relief valves are a type of pressure relief valve that is mounted directly on the pump. They are used to protect the pump from damage caused by excessive pressure, such as a blocked discharge line or a sudden increase in flow demand.
Internal relief valves consist of a spring-loaded poppet valve that is held closed by the pressure of the fluid in the pump discharge line. When the pressure exceeds the spring force, the poppet valve opens and allows some of the fluid to bypass back to the pump suction line. This reduces the pressure in the discharge line and prevents damage to the pump.
Internal relief valves are typically adjustable, so that the pressure setting can be changed to match the specific requirements of the pump and the application.
Here are some of the benefits of using internal relief valves:
They provide a simple and effective way to protect pumps from damage caused by excessive pressure.
They are easy to install and maintain.
They can be adjusted to match the specific requirements of the pump and the application.
