What Are The Differences And Connections Between Flow Dividers And Regulating Valves?

Splitter valves and regulator valves belong to different categories in valve classification. They are different in function, structure, and application scenarios, but they are also relevant. Here are the details:
Difference
function.
Split valve: Mainly used for separation, distribution or mixed media. It can distribute fluid from one inlet to more than one outlet in a certain proportion, or it can mix the flow of multiple media in a certain proportion to achieve flow distribution and proportional control. For example, in air conditioning system, the flow divider valve distributes refrigerant evenly across multiple evaporators to ensure consistent refrigeration performance in each region.
Regulator valve: Primarily used to regulate the media flow rate, pressure and other parameters. It can automatically change the valve opening according to control signals, so as to precisely control the flow rate, pressure or liquid level of the medium to meet process requirements. For example, in chemical production, the regulator controls the pressure inside the reactor to ensure that the reaction takes place under suitable conditions.
Structure
divider valve: Flow divider valves include three or four pass plug-in valves, three or four pass ball valves and distribution valves. Their structure usually consists of one inlet and multiple exits, with special internal channels for diverting or merging fluids. For example, a three-way valve changes the flow direction of a fluid by rotating the ball to achieve flow diversion or merging.
Control Valves: Control valve has a variety of structures, including single-seat control valves, two-seat control valves, angle control valves and sleeve control valves. The structure usually consists of a valve body, valve core, valve seat and actuator. The The actuator moves the core and changes the flow area between the core and valve seat, thus adjusting the flow rate of the medium.
Application Scenarios
Diverter valves: Widely used in chemical production to transport or mix liquids, such as heating systems, air conditioning systems, water supply and drainage systems, multi-channel ingredients. In the heating systems of high-rise buildings, for example, diverter valves distribute hot water evenly among each radiator, ensuring even heating across all floors.
Control valve: mainly used in chemical industry, petroleum, electricity, metallurgy and other automatic control control system that requires accurate control of parameters such as media flow and pressure. For example, in petrochemical industry reaction vessels, the regulator automatically adjusts the feed flow of the feedstock to ensure the stability of the reaction and the quality of the product, depending on the temperature, pressure and other parameters.
Relationship: all valves: both the Both diverter valves and regulator valve are valve types, have the function of controlling fluid flow, play an important role in piping systems.
There is some overlap: in some cases, the functions of distributors and regulators may overlap to some extent. For example, some shunt valves with flow regulation function can regulate the flow rate of each branch to some extent while implementing the shunt, while some regulating valves can also be used for the distribution of fluid under certain conditions.
Commonly used combination: In actual industrial production or piping systems, diverter valves and regulator valves are often used together for more complex fluid control functions. For example, during chemical production, diverter valves are used first to distribute raw materials to different reaction vessels and then to install regulator valves at the inlet of each reaction vessel to precisely control parameters such as feedstock flow and pressure inside the reaction vessel.
