Large Bore Pneumatic Triple Eccentric Butterfly Valve

Let's first share a set of practical parameters to help you make an informed choice: the nominal diameter ranges from DN50 to DN1200, covering almost all common pipe sizes; the working pressure can withstand PN1.0 to PN4.0MPa, meeting the pressure requirements of conventional industrial scenarios such as chemical engineering and water supply; it also has a wide temperature adaptation range, working normally in environments from -20℃ (low temperature) to 300℃ (high temperature). In terms of materials, you can choose from cast iron, cast steel, or stainless steel; the sealing surface is made of nitrile rubber or polytetrafluoroethylene, so you don't have to worry about leakage. Moreover, the connection method is flange, which fully complies with the national standard GB/T 12238. It can be installed directly on-site without additional size modifications, saving a lot of construction time.

Friends who have used pneumatic valves know that response speed and sealing performance are crucial. This pneumatic butterfly valve can open and close in as fast as 0.5 seconds, nearly twice as fast as ordinary pneumatic valves. When the production line needs to adjust the medium urgently, it will never let you down; the butterfly plate adopts an eccentric design, fitting tightly with the valve seat, and the leakage rate is even lower than the national standard requirement. Whether it's for clear water, oil products, or slightly corrosive gases, it can seal tightly. In addition, the inside of the valve body is anti-corrosion treated, so even in working conditions with low acid-base concentration, it can be used for five to six years without easy damage, with a service life more than twice that of ordinary butterfly valves.
