Motorized eccentric butterfly valve is composed of soft seated double eccentric butterfly valve or metal seated triple eccentric butterfly valve and on-off or regulating type actuator, which control of water and other media compatible with the materials of construction.Standard unit of motorized eccentric butterfly valve is power-to-open and power to close, stays in last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a flat gear system rotates the disc. The motor is automatically stopped by internal cams striking micro switches at both open and closed positions. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the valve position.
