D71J right folder rubber lined butterfly valve
Rubber lined butterfly valve disc to install the pipe diameter direction. In the cylindrical channel of the valve body, disc-shaped disc around the axis of rotation, the rotation angle between 0 ° ~ 90 ° rotation to 90 ° when the valve is open all license conditions.

Rubber lined butterfly simple structure, small size, light weight, only a few parts. And just rotate 90 ° to quickly open and close, easy to operate, the valve has a fluid control features.

Rubber lined butterfly simple structure, small size, light weight, only a few parts. And just rotate 90 ° to quickly open and close, easy to operate, the valve has a fluid control features. Flange rubber lined butterfly valve in the fully open position, the thickness of the disc is the only resistance in the medium flows through the valve when the valve pressure drop is small, it has a better flow control characteristics. The rubber lined butterfly bomb seal and metal seal two seal type. The elastic sealing valves, seals can be mounted on the body or attached to the disc around
