ELECTRIC ACTUATORS SERIES EL-750

1. Due to characteristics of valve, the electric actutor must be able to provide high start up torque with full load whenever the valve is at open, closed or any other position. Valtorc EL-750 sries electric actuators are designed for such working requirement. 2. Gear driving unit is made of alloy steel with heat treatment featuring high strength, excellent wear rsistance and long term fatigue load impact. 3. The crank handle is designed as d驩tachable to minimize the dimension of the actuator. 4. The intgral construction of the wormgear and drive shaft provides long term dependable opration with...
