Modern Design Electric Butterfly Valve New Technology Product in China
Summary
Eccentric rubber sealing butterfly valve has the unique eccentric structure, and with good cut-off performance. It enable to make control and shut off. Through output shaft's movement of actuator to realize the valve stem (valve plug) revolving, thus make the valve's throttling area changed to realize controlling the fluid ‘s pressure, flow and temperature.
Characteristics
1, The valve disc and seat sealing face contact with the circular cone surface, for this, it needs only small output torque to close the valve and is characterized for very high pressure drops;
2, In the case of high press drops or high temperature, we recommend stellite full surface of disc and seat ring.
3, It has good cut-off performance and can achieve VI for seat leakage.
