Three lengthened welded ball valve performance specifications: Nominal: PN1.6,2.5,4.0,6.4MPa strength test pressure: PT2.4,3.8,6.0,9.6, MPa low pressure gas seal test pressure: 0.6MPa Q61F- (16- 64) C Applicable medium: Q61F- (16-64) C water, oil, gas Q61F- (16-64) P nitric acid Q61F- (16-64) R acetate class Temperature: -40 ~ 280 ℃ three lengthened welded ball valve connection: welding, socket welding and so on. Manufacturing Material: 201,304,316,316L, carbon steel. Three-piece welded extended in the past three-piece ball valve is substantially lengthened butt welded pipe on both sides, to make up for the past welded ball during use due to some unnecessary short butt welded parts in the installation and construction caused trouble. Lengthen the pipe so that the pipe connections connect more closely, more effectively prevent leakage during use, the connection is unstable and so on.
