Fine and small regulating valves, also known as self balancing valves, flow control valves, flow controllers, dynamic balancing valves, and flow balancing valves, are intuitive and simple flow regulation and control devices. The regulating valve structure is composed of an electric or pneumatic actuator and a valve body. There are mainly two types of straight stroke: straight single seat and straight double seat. The latter has the characteristics of large flow capacity, small imbalance, and stable operation, so it is usually particularly suitable for situations with high flow rate, high pressure drop, and few leaks.

 

The function of precision and small electronic electric control valves

 

The application of flow control valves in the pipeline network can be directly designed according to the valve. Under the action of water, the valve can automatically eliminate the residual pressure head of the pipeline and the flow deviation caused by pressure fluctuations. No matter how the system pressure changes, the set flow rate remains unchanged. These functions of the valve enable the flow control of the pipeline network to be completed in one go, transforming the network adjustment work into simple flow distribution and effectively solving the hydraulic imbalance of the pipeline network. Flow regulating valves are mainly used in centralized heating (cooling) and other water systems to distribute the flow of the pipeline network as needed, eliminate hydraulic imbalance in the water system, and solve the problem of uneven heating and cooling. These types of valves should generally be installed horizontally in pipelines.

 

The principle of compact electronic electric control valve

 

The flow capacity of a valve only depends on the structure of the valve itself. When calculating the required valve flow capacity, attention should be paid to the significant differences in the flow state inside the valve due to different media or flow conditions.
