Product Features
·Turbine manual butterfly valve simple structure, large output torque,
can control large diameter butterfly valve.
·Just rotate 90 ° to quickly open and close, easy to operate,
while the valve has a good fluid control characteristic.
·Butterfly valve in the fully open position, the disc thickness is only resistance when the medium flows through the body, produced by the valve pressure drop is small.
·Unique three eccentric design, good sealing performance, can achieve zero leakage.
