Stainless steel one-piece flanged ball valve is small, easy installation features, but also has the advantage of national standard flanged full bore easily leak in one fell swoop changed the previous ways flanged ball valves flow is small, easy to leakage of solid disease, but also to solve the national standard flange Ball too bulky weaknesses, but the body can be refined with the casting process, elegant appearance. Full bore, large diameter capacity, connection dimensions conform to standard wide flange ball is expected to be widely used on an increasing number of channels. Connection: Flange nominal diameter: 1/2 "-4" Medium: extensive water, oil, steam, nitric acid, acetic acid, etc. Applicable Applicable temperature: -40- + 150 degrees without damaging the high pressure valve Valve seat: good material and the opening and closing performance PTFE .. Working pressure:. 1.6P ~ 2.4 ~ 6.4 hoisting force N:. 300-400 Main material:. 304, 316, WCB design and production using:. ANSI standard design and production its safety and quality of processing payment are subject to stringent domestic and foreign markets, and has been recognized by customers a stainless steel one-piece flanged ball valve advantages: 1, fluid resistance, ball full bore little flow resistance. 2, simple structure, small size and light weight. 3, close and reliable. It has two sealing surfaces, and valve sealing surface material widely used kinds of plastic, sealing, and can be completely sealed. In the vacuum system has also been widely used. 4, easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. 5, easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient. 6, in the fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface. Second, one-piece stainless steel flanged ball valves technical parameters: Nominal Diameter: DN15-DN100 Connection: Flange PN: 1.6-4.0MPa Temperature range: -20 ~ 232 ℃ ~ 350 ℃ Suitable medium: water, oil, gas and some corrosive liquid (WOG) Material: carbon steel, stainless steel and other brands: Kai standard Packing: wooden three, one-piece stainless steel flanged ball valve manufacturing standards: the design and manufacture standard: GB / T 12237-2008 standard length of the structure: GB / T 12221-2005 Flange standard: GB / T 9113 pressure and temperature rating: GB / T 12224-2005 test inspection standards: GB / T 13927-2008 four, one-piece stainless steel ball valve flange effect: This product is a manual valves. Ball is a sphere with a circular channel for opening and closing pieces, turning ball with stem to achieve open and close the valve action. Valve opening and closing parts is a hole in the sphere of rotation around the vertical axis of the channel in order to achieve the purpose of opening and closing of the channel. Ball is mainly used for pipes and cut off or connected media devices, can also be used for fluid regulation and control, valve fluid resistance is small, simple structure, small size, light weight, compact, reliable, easy operation and maintenance, does not cause the valve sealing surface erosion, a wide range. The products are all stainless steel parts are made of acid-proof materials, sealing with silicone rubber or PTFE material food, in line with food hygiene standards. Widely used in food, wine, beverage, dairy, pharmaceutical and bio-chemical engineering and other industries.
