German AVK valves, AVK valves models, AVK valves prices

AVK valves are also known as self-acting balance valves, flow control valves, flow controllers, dynamic balance valves, and flow balance valves. They are intuitive and simple flow regulation and control devices. When applied in pipe networks, flow control valves can set the flow rate directly according to the design. Under the action of water, the valve automatically eliminates flow deviations caused by residual head and pressure fluctuations in the pipeline. Regardless of how system pressure changes, the set flow rate remains constant. These functions allow pipe network flow regulation to be completed in one step, turning network balancing into simple flow distribution, effectively solving hydraulic imbalance in pipe networks. Flow control valves are mainly applied in water systems such as centralized heating (cooling), enabling on-demand flow distribution in pipe networks, eliminating hydraulic imbalance in water systems, and resolving uneven heating or cooling issues.

AVK valves operating principle

By receiving signals from industrial automation control systems (such as: 4~20mA), the valve is driven to change the cross-sectional area between the valve core and valve seat, thereby controlling process parameters such as flow, temperature, and pressure of the pipeline medium. This achieves automatic regulation functionality.

AVK valves structure

Self-acting pressure control valves do not require external energy sources such as power or air supply; they rely solely on the energy of the medium itself for actuation. They are energy-saving, environmentally friendly, and easy to use. After installation, simply set the pressure value to begin automatic operation. Therefore, they are increasingly widely used in applications where control precision requirements are not high and where power or air sources are lacking. However, during use, attention must be paid to the specifics of model selection to avoid accidents. During operation, pay attention to model selection and the installation environment. Therefore, a detailed understanding of the operating principle and structure of self-acting pressure control valves is very important.

AVK valves applications

The self-operated pressure regulating valve (hereinafter referred to as the pressure valve) is an energy-saving product that automatically regulates pressure by relying solely on the pressure changes of the medium itself, without requiring an external energy source. It integrates measurement, actuation, and control functions. It is widely used in industrial sectors such as petroleum, chemical, metallurgy, and light industry, as well as in urban heating and space heating systems. This product can be used as a pressure control device for non-corrosive media such as liquids, gases, and steam [maximum temperature 350 °C].
