Q347F forged steel fixed ball

Shanghai crown ring Valve Manufacturing Co. of "G" crown ring plate forged steel fixed ball, Q347F forged steel valve structure and uses three fixed split connection forged steel fixed ball valve, the valve body in two lines along with the valve seat portion channel control cross-section perpendicular to the axis formed segmented into three parts, the entire valve stem symmetrical along the central axis around which the pipe is mainly used for cutting, distribution and change the direction of media flow. First, forged steel valve structure and purpose: Three split connection forged steel fixed ball applies to: chemical, petroleum, natural gas, metallurgy, and other industries and media containing hydrogen sulfide, impurities, corrosion serious long distance gas pipeline. Fixed worm main performance requirements for valve, the valve body in two lines along with the valve seat portion perpendicular to the axis of the channel cross section is divided into three parts, the entire valve stem symmetrical along the central axis around which the pipe is mainly used for cutting , distribution and change the direction of media flow. Its large pivot structure to ensure precise ball at high pressure center position to ensure the accuracy of the valve operating performance; standard seat using a spring structure, the seat to the ball, to ensure a certain amount of import and export bi-directional sealing performance; the use of self discharge valve with the valve body cavity can be discharged outwardly; pivot adopt anti-blowout protection structure, effectively prevent leakage; bearing low friction coefficient, so that the torque is reduced to a minimum, easy to open and close the valve; stem and the body effective contact, so that the superior anti-static grounding device performance. With excellent performance, high reliability, versatility, reasonable prices and other advantages. Second, the main performance parameters: test pressure (MPa) Nominal (MPa) pressure level (Class) 1.6 2.5 4.0 6.4 10.0 16.0 25.0 150 300 400 600 900 1500 2.4 3.8 6.0 9.6 Strength Test 15.0 24 37.5 3.1 7.8 10.2 15.3 23.1 38.4 Sealing Test 1.8 2.8 4.4 7.0 2.2 5.6 7.5 11.0 17.6 27.5 11.2 16.8 28.1 0.5-0.7 airtightness test temperature PTEE≤150 ℃ PPL E≤300 ℃ Carbon ≤350 ℃ Suitable medium C: water, oil, steam P: Nitric acid (temperature ≤200 ℃) R: acetic acid type (temperature ≤200 ℃) forged steel fixed ball valve http://www.ghval.com/productlist/qf http://www.ghval.com/product/qf/122.html Shanghai -1.html
