Ball valves are widely used in various industrial sectors due to their simple structure, excellent sealing performance, and ease of operation. However, during long-term use, ball valves may develop leaks. Leaks not only lead to the waste of media but can also disrupt the normal operation of the system and even pose safety risks. Common Reasons 1. Aging or Damage of Sealing Materials The sealing pe...

The wafer ball valve is a valve widely used in industrial pipeline systems, recognized for its compact structure and efficient performance. Advantages of Wafer Ball Valves 1. Compact Design: The wafer ball valve adopts a wafer-type design, with its valve body clamped between two sections of piping using bolts. Compared to traditional flanged ball valves, the wafer ball valve has a more compact str...

The fully welded ball valve and the ordinary ball valve have significant differences in structure, characteristics, and applications. 1. Structural Differences Fully Welded Ball Valve: The fully welded ball valve adopts a fully welded structure, with no gaskets between the valve body and valve body, and is welded as a whole. This eliminates the need for gaskets or packing typically required in tra...

Ball valves are mainly used in pipelines to cut off, distribute, and change the direction of medium flow. The ball valve designed with a V-shaped opening also has good flow regulation function. The opening and closing component of a ball valve is a sphere, which rotates 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing. Ball valves have the advantages of lo...

There are many types of structures for ball valves, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. It is used on pipelines to shut off, distribute, adjust flow rates, and change the flow direction of the medium. O-type Ball Valves The body of the O-ring ball valve is equipped with a ball with an intermediate through hole inside, and there is a through...

At present, the commonly used hardening processes for the surface of metal hard sealed ball valves mainly include the following: (1) The surface of the sphere is welded (or sprayed) with hard alloy, with a hardness of over 40HRC. The process of surfacing hard alloy on the surface of the sphere is complex, with low production efficiency, and large-scale surfacing can easily cause deformation of the...
