An Orifice regulates the flow rate of fluid within the unit. The orifice size is relatively small, which means it restricts the flow of fluid passing through it. This restriction can be beneficial in certain hydraulic applications where precise control over the flow rate is required.Attributes:• Provide precise control over fluid flow rates• Can regulate and control fluid pressure within a unit, ensuring optimal operating conditionsApplications:An Orifice controls the flow rate, pressure, and characteristics of fluid passing through it, It achieves this by creating a restriction in the flow path, leading to changes in velocity, pressure, and flow profile.
