    Cast Iron Motor Operated Motorized Butterfly Valves

    This wafer-type valve is operated by an electric actuator for convenient remote operation. The dynamic sealing of the disc is achieved with low torque. An EPDM stem isolated from the valve body prevents stem seizure. It can be equipped with an on/off type actuator, a modulating type actuator, or an intelligent type actuator. This valve is widely used across the chemical, petroleum, metallurgy, and electric power industries.
