They are stable and reliable in usability, very easy to operate, rotate 90 degrees.
Small and lightweight, can be installed in any position pipeline.
When installing the valve, the direction of pipeline media flow can be disregarded, supporting bidirectional flow.
Groove butterfly valve due to the principle of three eccentric structure, the sealing surface of the valve plate and the valve seat sealing between the valve plate and the valve seat is to rely on the torque of the transmission device so that the valve plate is pressed to the valve seat. Positive flow state, the higher the medium pressure sealing squeeze the tighter. When the flow channel media countercurrent with the media pressure increases between the valve plate and the valve seat unit pressure is less than the media pressure, the seal began to leak.
