Regarding double-eccentric butterfly valves
Thread Content
High-performance double-eccentric butterfly valve! I would like to ask the experts here. In the fields you are familiar with, those operating conditions are used the most. Sealing: RPTFE or hard sealing with an O-ring. Is it suitable for water supply and wastewater treatment?
The regulation of ordinary media at normal temperature and low pressure can be achieved using double-eccentric butterfly valves
Normally, it is sealed with RPTFE or PTFE; if an O-ring seal is used, imported high-temperature resistant O-rings should be purchased. For water supply and sewage systems, a center-line butterfly valve is sufficient
High-temperature air below 200°C is commonly used for pneumatic butterfly valves in the air separation industry
