Butterfly Valves - Lug Style

Learn about Lug Style Butterfly Valves

Lug Butterfly Valves
Lug-style valves have mounting threads on both sides of the valve body. This allows the lug butterfly valve to be installed into a system using two sets of bolts and no nuts. The valve is installed between two ANSI/ASME pipe flanges with a separate set of bolts for each flange.


Electric Actuated Butterfly Valves
Valworx electric actuators rotate an output drive to open and close butterfly valves. Electric actuators provide a reliable and economical method of operating these valves from a remote location. For modulating valve applications, an electric actuator with EPS positioning can control the valve flow with a 4-20mA or 0-10v command signal.


Air Actuated Butterfly Valves
Rack and pinion quarter turn air actuators provide a simple and reliable method of automating butterfly valves. Actuators are available in spring return or double acting. Spring return actuators use air pressure to open and springs to close the valve (failsafe). A double acting air actuator uses air to open and air to close.


Manual Butterfly Valves
Butterfly valves are used to control flow in a pipe line. Rotating a disc within the valve body 90° opens or closes the flow passage. The butterfly valve can be operated with the 10-position locking hand lever. Butterfly valves are mounted between two pipe flanges for easy installation and maintenance.
