Motorized butterfly valve  Resilient Seated Butterfly Valve,is also referred to as “concentric”,"rubber lined" and “rubber seated” butterfly valve,has a rubber (or resilient) seat between the external diameter of the disc and the internal wall of the valve.

Butterfly valve is a quarter-turn valve that rotates 90 degrees to open or close the media flow. It has a circular disc, also known as the butterfly, found at the center of the body that functions as the closing mechanism of the valve. The disc is connected to an actuator or handle through the shaft, which goes through from the disc to the top of the valve body.

Butterfly valve is also used as flow regulalting valve,if the disc does not rotate to a full quarter-turn, it means the valve is partially open,we can regulate the flow of fluids by various openning angle.

Resilient Seated Butterfly Valve Lug type,the most compact design with short face to face.it's fit between two flanges,with studs passing from one flange through other. The valve is held in place and sealed with gasket by the tension of studs.A resilient seated butterfly valve lug type is a lightweight, maintenance-free, cost-effective, and reliable solution to various applications.

Motorized butterfly valve  ,is usually used where the valve is at the end of the pipe since there is no 2nd flange to secure the studs. Instead, lugs are cast on the valve with tapped holes which matches the bolt pattern for the size and pressure classification of the flange. Bolts are passed through the flange holes and are threaded into tapped holes of the lug.
