Centrifugal pumps may be strong and sturdy, but that does not make them immune to damage. These types are usually used in places that require heavy mechanical structures used to pump different types of Fluids for diverse purposes. These liquids have different thicknesses and thermal properties. As such, the thickness and thermal properties of the liquids will affect the centrifugal pumps. To protect the centrifugal pumps, diverse types of valves are usually used in mechanical systems. These valves are always differentiated by many factors, including the actuators. You can have an electric control valve, a pneumatic controlled valve, and hydraulic control. The electrically controlled valve will have its process controlled by the electric motor in the system. The hydraulic and pneumatic controls work with a non-compressible medium and a compressible medium, respectively. Another way to differentiate the different types of valves is through their functions. Some valves work by protecting the centrifugal pumps with minimum flow control. This type of valve ensures that the flow entering the pump is maintained at a certain level.
Minimum flow valves control any type of liquid flow, which in turn will protect and extend the lifespan of the centrifugal pump. Minimum flow pumps are not the only options you have when it comes to choosing a valve for your centrifugal pumps. However, amongst other valve options, it stands out as the best. Because whether the liquid is very thick or it is coming at a very high temperature, it has little chance of damaging the valve as long as the flow is controlled. This is not the only advantage of using a Minimum Flow Valve. There are other benefits of choosing this valve, which we will be discussing in this guide.
