The JFlow Controls JFER series electric actuator contains a shell made of aluminum allow, with anodic oxidation treatment and a polyester powder coating. It is corrosion resistant and the enclosure is IP67, NEMA 4 and 6, IP68 optional. If without power, the actuator can be operated via the handle. The space heater is used for controlling temperature in order to avoid condensing internal housing. The actuator contains accurate worm and worm gear transfer large torque efficiently, high efficiency, low noise (max 50 dB), long life, with self-locking, prevent inversion, as stable and reliable transmission parts. There is no need to refuel.
Additionally, the installation size meets international standard ISO 5211/DN3337. The controlling circuit meets the single-phase or three-phase power supply standard, circuit layout is reasonable and compact, and terminals meet various additional functional requirements effectively. The actuator bolt attaches to the shell and does not come off when the shell is removed.
