Those who are familiar with the valve industry will find that the current material price of Yuhuan copper valve manufacturing is often proportional to the hardness. That is to say, the higher the hardness of the material, the more expensive it is, but sometimes high hardness does not mean that the possibility of application is high.
In fact, with the development of modern materials science, while considering the hardness of materials, other properties can also be taken into account. Therefore, other properties of materials with high hardness will not be poor. For most valves, hardness is one of the indicators, and for American standard flanged globe valves, hardness is one of the hard indicators. The reason is very simple, the opening method of the American standard globe valve is related. That is to say, the American standard flanged globe valve is a forced sealing valve, which is characterized in that a certain pressure must be exerted on the valve whether the valve is closed or open. The greater the friction between the valve and the filler, the greater the force required. In this case, there are higher requirements for the overall material strength and hardness to prevent damage to the American standard globe valve. If the material is made of relatively soft stainless steel, the valve can easily deform under the influence of this forced sealing force.
