Butterfly valve consultation! Which one is the best! Seeking high-quality help, for use in PSA
Thread Content
I need a butterfly valve with two-way sealing; gas flows in one direction sometimes and in the opposite direction other times. The pressure difference across the valve should not exceed 1 MPA, and there may be situations where a vacuum of -97 KPa is created. Which manufacturer can supply a valve that meets these requirements? Or which company has used similar valves? Such valves are typically used in PSA systems. Please recommend some options for me. Thank you!
Suzhou Newway Valve Co., Ltd., Suzhou High and Low Pressure Valve Factory Co., Ltd., Jiangnan Valve Co., Ltd., and so on
For this, a soft seal with three eccentricities should be a good choice; however, it’s important to select one of good quality. The most crucial aspects are the sealing surface and the sealing mechanism
Reply to 3# wow0011: Well, thank you. I’ve seen many examples of two-way double-eccentric designs on the internet; anyone who has used PSA and can recommend it would be great!
I have worked on this type of application before; such butterfly valves were previously used in conjunction with the pressure swing adsorption units.

Taiwan Jetstream Valves and Tianjin Bonasway Valves are both professional manufacturers of butterfly valves. Suzhou Newway Valves Co., Ltd. is widely used in petrochemical projects both domestically and internationally, and it enjoys a good reputation. Suzhou High Pressure Valve Factory Co., Ltd. is a highly reputable valve brand in China. Jiangnan Valves Co., Ltd. excels in the research and development as well as production processes of butterfly valves. These brands are often mentioned by customers when I communicate with them, and they enjoy a great reputation among users.
Sichuan Air Separation Equipment Valve Company – our company has been engaged in this field all along
Tianjin Tanggu Watts Valves, a professional manufacturer of butterfly valves – TWT is fully capable of meeting this requirement; its Mosbore butterfly valves are also very renowned – you can contact *a*--
I recommend Suzhou Newway, Tianjin Watts, and Henan Shangdie
What was said upstairs isn’t very professional – this device has quite high requirements for butterfly valves of this type. It’s better not to use it from manufacturers that are not specialized in production.
