Forged Stainless Steel A182 F316L Trunnion Mounted Ball Valve

Forged steel ball valve is a key valve commonly used in industrial pipeline systems, widely used in fields such as petrochemicals, natural gas, and power.

Firstly, forged steel ball valves achieve fluid blockage and control through the rotation of the sphere. The sphere, as the core component of the valve, changes the opening and closing of the fluid channel through rotation. When the sphere rotates to contact the valve seat, it can achieve fluid blockage and sealing. When the sphere rotates to the point where it comes out of contact with the valve seat, the channel can be fully opened to achieve smooth fluid flow. The working principle of this rotation can provide highly reliable sealing performance and flow control capability.

Secondly, forged steel ball valves have high pressure resistance and corrosion resistance. Due to its widespread application in industrial pipeline systems, forged steel ball valves need to withstand high pressure and temperature. Therefore, it is made of high-strength steel, such as carbon steel, alloy steel, etc., to ensure its pressure resistance. Meanwhile, the forged steel ball valve adopts special anti-corrosion treatment during the manufacturing process, which improves its corrosion resistance and adapts to various acid, alkali and corrosive media.

In addition, forged steel ball valves have the characteristics of fast switching and tight sealing. Due to the rotation mechanism of the sphere, forged steel ball valves can achieve fast switching operation and fast response speed. Meanwhile, the forged steel ball valve adopts a double sealing structure, ensuring the tight sealing of the valve and preventing leakage. The characteristics of fast switching and tight sealing make forged steel ball valves suitable for situations with high requirements for flow control and air leakage.

Forged steel ball valves have the characteristics of simple structure and easy maintenance. It is composed of a small number of components, with a compact and simple structure, reducing the probability of failure and maintenance costs. Meanwhile, the ball of the forged steel ball valve can be disassembled for easy maintenance and repair work.

In summary, forged steel ball valves achieve fluid blockage and control through the rotation of the sphere, and have high pressure resistance and corrosion resistance. It also has the characteristics of fast switching and tight sealing, suitable for situations with high requirements for flow control and air leakage. Meanwhile, forged steel ball valves have the characteristics of simple structure and easy maintenance, which can provide reliable usage effects and long-term stable operation.

The three-part connection forged steel fixed ball valve divides the valve body into three parts along the section perpendicular to the valve channel axis at the two valve seats. The entire valve is symmetrical about the center axis of the valve stem, and is mainly used for cutting, distributing, and changing the direction of medium flow in pipelines. Its large pivot structure ensures accurate center position of the sphere under high pressure, ensuring good operational performance of the valve; The standard valve seat adopts a spring structure, which pushes the valve seat towards the sphere, ensuring good bidirectional sealing performance at the inlet and outlet; By using the built-in discharge valve, the middle chamber of the valve body can discharge outward; The pivot adopts an anti blow out protection structure, effectively preventing leakage; Low friction coefficient bearings reduce torque to a minimum, facilitating valve opening and closing; The effective contact between the valve stem and valve body ensures superior performance of the anti-static grounding device. It has the advantages of excellent performance, high reliability, wide application, and reasonable price.
