Dimensions: 8 inches
Pressure rating: 300LB, capable of withstanding a working pressure of up to 4.8MPa.
Material selection: WCB, which is a high-quality carbon steel material with good mechanical properties and corrosion resistance and can adapt to a variety of working environments.
Structural design: Adopting a floating ball structure, the ball can automatically float under the action of the medium pressure to ensure the sealing performance. This design not only improves the sealing reliability of the valve but also reduces the operating torque, making the operation of the valve easier.
Applicable media: Suitable for a variety of media, including water, steam, oil products, etc., and is widely used in industries such as petroleum, chemical engineering, and electric power.
Shell strength test: Conduct the shell strength test according to the GB/T 13927 standard. The test pressure is 1.5 times the nominal pressure, and the duration is not less than 5 minutes. The test results show that there is no leakage in the valve body under the specified pressure, proving that it has good strength and sealing performance.
Sealing performance test: Adopt low-pressure and high-pressure sealing tests, which are carried out at 1.1 times and 1.5 times the nominal pressure respectively. The test results indicate that the valve can maintain good sealing performance under different pressures without any leakage.
Operating performance test: Test the operating performance of the valve by simulating the actual working conditions. The test results show that the operating torque of the valve meets the design requirements, the operation is flexible, there is no jamming phenomenon, and it can meet the needs of rapid opening and closing.
Durability test: Conduct multiple cyclic operation tests to evaluate the durability of the valve. After tens of thousands of opening and closing operations, the sealing performance and operating performance of the valve remain stable, proving that it has a long service life.
Fire performance test: Conduct the fire performance test according to the API 607 standard to simulate the sealing performance of the valve under fire conditions. The test results show that the valve can maintain sealing under the action of high-temperature flames to prevent the leakage of the medium, thus ensuring the safe operation of the industrial system.
