Lug Butterfly Valve

The butterfly plate of the lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0-90 degrees, which can play the role of flow regulation. When the butterfly plate rotates to 90 degrees, the valve reaches the maximum opening, easy to operate.

1.Introduction of Lug Butterfly Valve

The butterfly plate of the lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0-90 degrees, which can play the role of flow regulation. When the butterfly plate rotates to 90 degrees, the valve reaches the maximum opening, easy to operate.
The lug butterfly valve has good fluid control characteristics. When the lug butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics.

3.Advantage of the lug butterfly valve

1. When the lug butterfly valve is installed with the pipeline, the flanges on both sides are installed with bolts respectively, so that the valve body and the sealing surface of the valve body are not squeezed by the bolts, which is beneficial to the sealing life,
2. The lug can be easily installed in the discharge position.
3. The elastic seal is produced by torque.
4. The ingenious wedge design enables the valve to have the automatic sealing function of closing tighter and tighter, with compensation and zero leakage between the sealing surfaces.
5. Small volume, light weight, light operation and easy installation.
6. Lug butterfly valve can be equipped with pneumatic, electric, hydraulic and manual devices to meet the needs of remote control and program control.
7.The material of replacement parts can be applied to all kinds of media, and can be used for lining anti-corrosion (F46, gxpp, Po, etc.)
