ELECTRIC VALVE ACTUATORS
J+J electric valve actuators
The actutators are made of a robust plastic housing. The design places particular emphasis on user-friendliness.
The electrical connection is made via DIN cube plugs without opening the housing. The manual override can be switched on directly at the actuator and used without further tools.
The position indicator always clearly shows the current position of the valve. Large swivel angles of up to approx. 340° are possible.
J4C Series
25Nm – 300Nm | IP67
At the top is without a doubt the J4C series, which offers many possibilities with its fully digital electronics. The drive can be tailored exactly to your needs. The built-in RBG status LED always indicates the current operating status via different colors and flashing cycles.
Features / Options
In addition to the two potential-free limit switches and the freely adjustable cam system, this series is equipped with a thermostat-controlled control room heating, a torque protection circuit and a practical RGB LED.
There are many options available for this purpose:
- Emergency function via BSR battery pack (NC/NO)
- DPS positioner with non-contact Hall sensor for analog signals (V/mA). With input and output signal or output signal only
- 3 positions with center position for 3-way valves (standard 0°-90°-180°)
- various wiring variants
Brushless direct current motor
A brushless motor is characterized by the fact that the moving rotor and the stationary stator are not electrically connected. This eliminates the need for sliding contacts (motor brushes), which would be subject to wear due to mechanical abrasion and brush fire.
Wide range power supply
All drives of the J4C series are equipped with a wide-range power supply for common supply voltages, which self-adaptively detects the connected voltage.
Voltage range:
J4C “S”: 24-240VAC / 24-135VDC

J4C “B”: 12V AC/DC
J4C “H”: 230V DC (85-240V AC/DC)
