Modern industrial systems require not only complete shut-off of flows, but also precise control of their parameters. To solve these problems, a control ball valve is used, combining the functions of shut-off and control valves. This equipment allows you to smoothly change the flow rate of the medium, ensuring optimal technological processes. Its use is especially important in systems where precise dosing or maintenance of preset parameters is required.
Design and operating principle
The design of the control valve differs from the standard ball valve models. The main difference lies in the special shape of the shutter and the seat. The ball has a V-shaped or special profile hole. This feature allows precise flow control during partial opening. Consequently, a smooth change in throughput is achieved without sudden pressure surges.
Execution materials are selected according to the operating conditions. The case is usually made of stainless steel or carbon steel. Seals are made of fluoropolymer or other chemically resistant materials. Gearboxes or electric drives are often used for precise positioning. Therefore, management can be either manual or automated.
Industrial applications
This type of valve is widely used in various industries. First of all, it is used in the chemical and oil and gas industries. Here, taps regulate the flow of reagents, raw materials, and intermediates. They ensure accurate dosing of components in technological processes.
In addition, the equipment is in demand in heating and ventilation systems. It allows you to adjust the coolant depending on the ambient temperature. In the food industry, such taps control the flow of ingredients and finished products. As a result, production cycles are stable and resources are saved.
Selection and installation criteria
When choosing a regulating ball valve, several parameters are taken into account. The characteristics of the working environment are important: pressure, temperature, and chemical composition. The diameter of the conditional passage must correspond to the parameters of the pipeline. They also pay attention to the control range and control accuracy.
Installation requires a professional approach. It is necessary to ensure the correct orientation of the crane relative to the flow direction. For automatic systems, it is important to connect the drives and sensors correctly. Regular maintenance prolongs the service life of the equipment. Therefore, this ensures reliable operation of the entire system.
Thus, the regulating ball valve represents
