High Performance electric actuated butterfly valve Flow Control Modulating

 

 

High Performance Electric Butterfly Valve For Flow Control Wafer Type On Off

 

 

FEATURES

 

 

 

1, easy to open and close, labor-saving, small fluid resistance, can be operated frequently.

2. Simple structure, small size and light weight.

3. Mud can be transported and the liquid is accumulated at the mouth of the pipe.

4. Under low pressure, a good seal can be achieved.

5, the adjustment performance is good.
