Description & Features

As a component used to realize the on-off and flow control of the pipeline system, the midline butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. In the known butterfly valve technology, the sealing form of the sealing structure, sealing materials for rubber, PTFE, etc.

● PTFE Lined Wafer Resilient Seated Butterfly Valve is bi-directional flow and possible at maximum operating pressure and because of valve port is corresponds to the piping diameter, high flow capacity is guaranteed.

● Full PTFE Lined Wafer Butterfly Valve is easy of maintenance, sealing parts is changeable.

● Mud can be transported with minimal fluid accumulation at the mouth of the pipe.

● At low pressure, good sealing can be achieved.

● Easy to open and close quickly, labor saving, fluid resistance is small, can often operate.
