Wafer type butterfly valve

1. PROFUCT PROFILE

Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange.They feature threaded tapped lugs positioned on the valve flanges for bolt connections. According to actual piping conditions, lug type butterfly valve can be manufactured according to different flanges standards, such as ASMEB16.1, EN1092, AS2129, DIN2501, BS4504, JIS10K. Lugged type butterfly valve can be mounted onto the piping ends as exhaust valve too. Prosper Flow can manufacture the lugged butterfly valve according the standards of EN593, API609 and ASME B16.34 with the sizes of 2″~24″ (DN50~600mm).
