PN40 Butterfly Valve

Butterfly valve is used for isolating or regulating flow and its function allows for quick shut off. There are many different kinds of butterfly valves, each adapted for different pressures and different usage in the industry. Products Range Type Available: Flanged type. Sizes Available: DN50mm to DN1200mm (2" to 48") Pressure Range: PN (MPa): 1.0, 1.6, 2.0, 2.5 Materials Standard: Others on request Basic Design: ANSI/AWWA C504 Face to Face Dimension: BS5155 Short, ISO5752 (Series 13), DIN 3202 F16 Inspection & Testing: API 598, Flanged End Dimension: DIN PN10/16/25, ANSI B16.1, BS4504, ISO PN10/16, JIS B2212/2213, BS 10 Table D, BS 10 Table E Top flange: ISO 5211 Suitable Mediums: Fresh water, sea water, gas, oils, acids, alkalis, etc Suitable Temperature: -26℃-82℃ Main features 1. The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose if pressing out the sealing surface has small frictional resistance. When shutting off, it cleses more and more, so this makes sealing performance reliable, Opening can ensure that the sealing. 2. The special geometric structure makes the butterfly valve free of defect that other butterfly balves are unable to be sealed will due to excessively opening, so as to gurantee good sealing of the surface. 3. The double eccentric butterfly valve structure can gurantee that the valve fundtions mormally under high prssure and overcome the shortcomings that other valve easily leak due to sest deformation when they work under high pressure.
