Lug butterfly valves are connected with threaded inserts at both sides of the valve body,and suits to be installed into a system using two sets of bolts and no nuts. The valve has to be installed between two flanges using a separate set of bolts for each flange. With this setup each side of the piping system could be disconnected without disturbing the other side.
 
Usually a Lug butterfly valve, when used in dead end service, has a reduced pressure rating. The body lining of rubber vulcanization ensure a stable driving torque. Furthermore, the ends of Body Rubber vulcanization are easy to plug water line to fulfill various forms of the flange sealing requirements.
 
This kind of valve is designed to have minimized operating torque, a strong energy saving approach, customizable lever, worm gear, pneumatic apparatus, electronic apparatus or combination driving operation according to working requirements.
 
The main strength of the Lug-style butterfly valve consists in his professional design, high flow rate and low flow resistance.
 
Suitable for: fresh water, waste liquid, seawater, vapor, food, medicine, oils, Acids, Alkalis, Salts, etc. No leaking under rated pressure.
 
Application of this flange: replaceable seat (with back) use the special butterfly valve flange for installation; replaceable seat (without back) or valve body line with rubber seat apply to professional butterfly valve flange or welded flange, etc. various flange installation.
