Steel welded ball valve
Steel welded ball valve has been widely used in various fields in recent years. Relying on its quality and stability, steel welded ball valves have been widely used in various fields and have been fully affirmed and recognized. The service life of steel welded ball valves is much longer than that of steel butterfly valves and ordinary welded ball valves
Application scope of steel welded ball valves: city gas, city heating, petrochemical industry, shipbuilding, steel, pressure regulating stations, power plants, etc. On all kinds of pipeline equipment. Fully welded ball valves can operate reliably for a long time, require no maintenance, are easy to operate, and can be installed more quickly, saving engineering time and reducing engineering costs. The service life of the steel welded ball valve is the same as that of the pipeline, and the steel welded ball valve can be used for more than 10 years.
Uses of steel welded ball valves:
City gas: gas output pipelines, main lines and branch line supply pipelines, etc.
Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment.
Heat exchanger: opening and closing of pipes and circuits.
Steel plant: various fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
Characteristics of steel welded ball valves:
Steel welded ball valves will not have external leakage, because the valve seat is composed of carbonized Teflon sealing rings and carbon springs to withstand pressure and temperature. It has strong ability to change habits, and no leakage will occur within the indicated pressure and temperature range. The processing process of the sphere is tracked and inspected by leading computer inspection instruments, so that the processing accuracy of the sphere is high. Because the valve body material is the same as the pipe material, there will be uneven stress and will not be deformed due to earthquakes and vehicles passing over the ground, and the pipes are resistant to aging. The sealing ring body is made of %C (carbon) material to ensure no leakage (%).

Steel welded ball valve Function:
): No maintenance, adjustment and Smooth, easy to install, and operates reliably for a long time with low operating costs. The appearance adopts spray plastic treatment technology, and the luster is beautiful, which is already at the leading level in China. There will be no external leakage and other phenomena. The valve body is of welded construction, so the valve is lightweight and easy to insulate. The installation and adjustment mechanism is very simple, the operating handle can be removed and the installation is reversed.
): Since the valve seat is made of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to changes in pressure and temperature, and no leakage will occur within the marked pressure and temperature range.
): The processing process of the sphere is tracked and inspected by a leading computer inspection instrument, so the processing accuracy of the sphere is high.
): Because the valve body material is the same as the pipe material, there will be no uneven stress, nor will it be deformed due to earthquakes and vehicles passing over the ground, and the pipeline is resistant to aging.
): Integral fully welded, equal diameter and variable diameter channels, fixed ball and floating ball, double piston effect sealing system, automatically
written sealant type bearing.
): In order to prevent static electricity, steel balls and springs are installed between the valve stem and the ball as well as the valve stem and the stuffing box, which can maintain the conductivity of all parts of the valve and the valve body, allow current to pass through the area, and release static electricity. It not only avoids fire, but also avoids corrosion and achieves temporary blockage for timely repair.
): The anti-separation function of the valve stem is because the valve stem is affected by the pressure within the valve and always generates a force to escape, so the valve stem is designed into an anti-separation structure.
): Use a thrust washer of low-friction material to support the pressure facing the valve stem, so that the valve stem only serves to transmit torque.
