The Lug Type Concentric Butterfly Valve reduces the rotational torque and supports the shaft which effectively separates it from the valve body and avoids the shaft to wear of. The valve is polished to match the valve seat and improves the zero leakage requirement of the air tightness test, the opening and closing torque is small, and the service life of the valve seat is prolonged.

The stem seal is not easily deformed, and avoids the usual stem leakage. High precision and high strength, suitable for the installation of handles and other control devices. Strongly connected to the valve stem and valve plate, it has anti-vibration characteristics and is easy to replace. Good overall, easy to control the valve plate to open and close. It has the characteristics of no falling off, tensile, leak-proof and easy to replace. As a device for regulating or cutting off media in the pipeline. Suitable for handle control devices (DN50 ~ 300), worm gears, electric and pneumatic control devices.
