1.Compact structure: the maximum flow design is widely used in high voltage and frequent switch.

2. Free leakage body seal structure: smooth, double cover gasket of the body and bonnet at valve switch position and o ring, on this basis, it does not cause external leakage on the situation of fire, high temperature, shock absorption and uneven opening or closing torque.

3. Low torque operating: self-lubricating bearings mounted on friction stem cells lead to wear resistance, flexible operation and low torque.
