What Are the Advantages of SS Ball Valves?

SS ball valves are available in pneumatic, manual and electric types, generally used for cut-off media and flow control in industrial pipelines. Ball valves are commonly used in various sectors such as petroleum, chemical, power generation, aerospace, rockets, papermaking, nuclear energy, and widely used in liquid oxygen and liquid hydrogen delivery pipelines in nuclear and aerospace industries. Compared with china gate valve, wholesale butterfly valve, globe valves and other valves, SS ball valves from Utmost stainless steel ball valve manufacturer have the advantage of stronger sealing performance and corrosion resistance.

The characteristics of SS ball valves are: corrosion resistance, high temperature resistance, low temperature resistance, high pressure resistance, light weight and low cost. They are increasingly used in waterways and chemical pipelines, and are an important aspect of ball valve applications in large-diameter oil or natural gas pipelines.

Working principle of SS ball valve

SS ball valves use the rotation of the valve core to make the valve unblocked or blocked. The ball valve is light in switching, small in volume, can be made into a large diameter, reliable in sealing, simple in structure, easy to repair, and the sealing surface and ball surface are often in a closed state, not easy to be eroded by the medium, and have been widely used in various industries. SS ball valves and eccentric rotary plug valve are valves of the same type, only their closing parts are ball bodies, and the ball bodies rotate around the center line of the valve body to achieve the opening and closing of a valve. SS ball valves are mainly used in pipeline to cut off, distribute and change the flow direction of the medium.

Advantages of using SS ball valves

  • Anti-static function: A spring is set between the ball, stem and valve body to discharge the static electricity generated during the switching process.

  • In order to make the stem operate smoothly and flexibly for a long time, a thrust bearing can be used to reduce the friction torque of the stem.

  • Small fluid resistance, is the smallest fluid resistance among all types of valves.

  • The stem packing seal is not easy to be damaged, and the sealing ability increases with the increase of the pressure of the medium. The stem seal is reliable, because the stem only performs rotational motion instead of lifting motion.

  • Due to the good self-lubricating property of materials such as polytetrafluoroethylene, the friction loss with the ball body is small, so the service life of ball valves is long.

  • The bottom-mounted stem and the protruding step at the top of the stem prevent the stem from ejecting. If the stem seal is damaged due to a fire, the protruding step and the valve body can form a metal contact to ensure the stem seal.

  • Good sealing effect: The sealing method adopted by SS ball valves is to grind the valve core and the sealing ring to integrate them. The biggest advantage of doing so is to ensure the sealing performance of SS ball valves. It is worth mentioning that in vacuum systems, SS ball valves have been widely used.

  • Long service life: Many customers will ask about the service life of equipment when purchasing. If the service life of a device is short, it will not only bring maintenance pressure to the enterprise, but also increase the enterprise's cost and reduce work efficiency. However, the service life of SS ball valves is relatively long. Specifically, the equipment uses special materials, coupled with a reasonable structural design, making the valve's service life longer.
