German hpvalves valves hpvalves models hpvalves prices

hpvalves valves, also known as self-acting balance valves, flow control valves, flow controllers, dynamic balance valves, and flow balance valves, are intuitive and simple flow regulation 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, maintaining the set flow rate constant regardless of system pressure changes. These functions allow for one-time flow regulation in the pipe network, simplifying network balancing to basic flow distribution, and effectively resolving hydraulic imbalance in the pipe network. Flow control valves are mainly applied in water systems such as centralized heating (cooling), enabling on-demand flow distribution in the pipe network, eliminating hydraulic imbalance in water systems, and solving problems of uneven heating and cooling.

hpvalves valve 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 automated regulation functionality.

hpvalves valve structure

Self-acting pressure regulating 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. Once installed and the pressure value is set, they can be put into automatic operation. Therefore, they are increasingly widely used in applications where high control precision is not required and where power or air sources are lacking. However, during use, attention must be paid to the specificity of model selection to avoid accidents. During operation, care should be taken regarding model selection and installation environment. Therefore, a detailed understanding of the working principle and structure of self-acting pressure regulating valves is very important.

hpvalves valve applications

A 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 any external energy source. It integrates measurement, actuation, and control functions. It is widely applicable in industrial sectors such as petroleum, chemical industry, 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 liquids, gases, and steam with a maximum temperature of 350 °C.
