Additional Product Information
Casting is the material in the mold overall casting molding, its stress distribution is even, there is no limit to the direction of pressure. And the forging is made by the same direction of force compression, its internal stress has directional, can only bear directional pressure. The same material, the same wall thickness of castings and forgings, in strength and crystal structure, forgings are better than castings. For valves, the wall thickness of casting valves of the same weight class and material is thicker than that of forgings. Its compressive strength is equal to that of the forging. Casting is taller to the requirement of casting process, the biggest characteristic is can make more complex shapes, valve body structure and flow are irregular, casting can be one-time molding, as long as the process, can be cast out of the large diameter of the valve body,The density of forgings is better, but for too complex flow channel and appearance to a molding, often need to be modular, forging welding together again separately, thus the size of the forgings. Forging often does not produce complex, streamlined runner. Port of machining by cutting and become, within many sharp-angled transition, easy to cause uneven stress at the sharp corners, produce craze. Modular design of welded together at the same time, the forging of the valve seat diameter is relatively fixed, on some valve size, its diameter is small, influence the flow capacity. Causes the valve flow resistance to increase, the entire system efficiency reduction. Due to the limitation of large size valve forging technology and to save cost, many manufacturers usually adopt the structure of the forging parts at both ends and the center part of the valve body. Whether it's casting, forging.
