Steel welded ball valve
Steel welded ball valve has been widely used in various fields in recent years. Due to 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 pipeline equipment. Fully welded ball valves can operate reliably for a long time, require no maintenance, are simple to operate, and are more convenient to install, saving engineering time and reducing engineering costs. The service life of steel welded ball valves is the same as that of pipelines, and the service life of steel welded ball valves is 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 adaptability to changes and will not cause any leakage within the marked pressure and temperature range. The processing process of the sphere is tracked and detected by advanced computer detectors, so that the processing accuracy of the sphere is high. Since 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 material:
): Valve body: carbon steel., B steel
): Ball: stainless steel or
): Stem:
): Stem seal: perfluorinated rubber
): Ball seal: R (+C)
Standard features of steel welded ball valve:
): Diameter: ~
): Pressure: ~
): Working temperature: ℃ ~ +℃
): Adaptable medium: petroleum/gasoline, liquefied natural gas/liquefied petroleum gas, petrochemical industry, steel Plant, heating pipes, etc.
): Operation mode: handle, gear (vertical/horizontal), electric, turbine
Steel welded ball valve performance:
): No maintenance, adjustment and lubrication required , easy to install, long-term reliable operation with low operating costs. The surface adopts spray plastic treatment technology, which has beautiful gloss and is 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. It is very easy to install the adjustment mechanism. The operating handle can be removed and installed in reverse direction.
): Since the valve seat is made of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to pressure and temperature changes and will not cause any leakage within the marked pressure and temperature range.
): The processing process of the sphere is tracked and detected by advanced computer detectors, so the processing accuracy of the sphere is high.
): Since 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 pipes are resistant to aging.
): Integral fully welded, equal diameter and variable diameter channels, using fixed balls and floating balls, double piston effect sealing system, automatic
injection sealant type bearings.
): 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 prevents fire, but also prevents corrosion and achieves temporary cutting for timely maintenance.
): 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 disengage, so the valve stem is designed with an anti-separation structure.
): Use a thrust washer of low-friction material to support the pressure pushing toward the valve stem, so that the valve stem only plays the role of transmitting torque.
