Overview

The construction principle of electric flange ball valves is particularly suitable for manufacturing large-diameter valves. Electric ball valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants. The commonly used electric ball valves include clamp type electric ball valves and flange type electric ball valves.

Product Details

The DYQ941F electric ball valve has a simple structure and is composed of only a few parts, which saves data consumption; Small size, light weight, small installation size, small driving torque, pressure regulating valve, easy and agile operation, only need to rotate 90 ° to quickly open and close; And it also has good flow regulation function and sealing characteristics. In the application range of large and medium caliber, medium and low pressure, electric ball valves are dominant. When the electric ball valve is in the fully open position, the thickness of the valve plate is the resistance of the medium flowing through the valve body, so the pressure drop that occurs through the valve is very small, thus having good flow control characteristics.

Electric ball valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If requesting an electric ball valve for flow control, it is important to accurately select the size and type of valve.

The construction principle of electric ball valves is particularly suitable for manufacturing large-diameter valves. Electric ball valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also in the cooling water system of thermal power plants. The commonly used electric ball valves include clamp type electric ball valves and flange type electric ball valves. The clamp type electric ball valve is connected between two pipeline flanges with double headed bolts. The flange type electric ball valve has a flange on the valve, and the flanges on both ends of the valve are connected to the pipeline flange with bolts. The strength performance of a valve refers to its ability to withstand medium pressure. Valves are mechanical products subjected to internal pressure, therefore they must have sufficient strength and stiffness to ensure long-term use without rupture or deformation.
