Zpa Pecky MOA Series Electric Actuator
BRAND : Zpa Pecky ? ? ? ? Electric rotary multi-revolution actuators MODACT® MOA are designed for remote control of special valves installed in attended areas of nuclear power plants with reactors VVER or RBMK. The type series includes 5 sizes of electric actuators with tripping torque from 20 Nm to 2000 Nm. The actuators are suitable for controlling sliding valves and valves with nuts. For valves, the pitch angle of thread of the spindle nut must not be higher than 5°.
