The Difference Between Switch Type And Regulating Type Electric Valve
Electric valves are an automated control device used to control the flow of fluid media (such as water, gas, steam, etc.) in pipeline systems. In electric valves, the two common types are switch type and adjustment type, which have some differences in function and application. Firstly, let's take a look at switch type electric valves. Switched electric valves typically have two states, namely fully open or fully closed. They achieve the goal of switching medium flow by controlling the action of electric actuators (such as motors). Switch type valves are suitable for scenarios that require rapid switching of medium flow, such as in emergency situations where fluid supply needs to be quickly cut off. This type of valve typically has high reliability and durability.
Regulating electric valves have more control and regulation capabilities. They are designed to adjust the flow rate, pressure, or temperature of the medium by changing the opening of the valve. Regulating electric valves can maintain fluid stability under different medium conditions to meet specific process requirements. By controlling the opening of the valve, flow regulation and precise control of fluid parameters can be achieved. This type of valve is very common in many industrial applications, such as chemical, pharmaceutical, food and beverage industries.
In terms of use, switch type electric valves are commonly used in situations that require simple operations, such as as as a pipeline cut-off device or adjustment of fluid flow direction, while regulating type electric valves are more suitable for applications that require precise control of medium parameters, such as precise flow regulation or stable pressure control.
In addition, from the perspective of valve structure, switch type electric valves usually use structural forms such as ball valves and butterfly valves, which are easy to operate and have good sealing performance, while regulating type electric valves often use structural forms such as shut-off valves and diaphragm valves to ensure more accurate flow regulation and pressure control.
Overall, the function of switch type electric valves is relatively simple, mainly used for quickly cutting off fluid flow, while regulating type electric valves have stronger control and adjustment capabilities, suitable for situations where precise control of fluid parameters is required. The selection of which type of electric valve should be based on specific application needs and process requirements¡£
