The actuators NE with PCU-board can be used as an efficient 90 ° electric actuator for the actuation of butterfly valves and ball valves in positioning operation. The analog input signal 4 ... 20mA is converted proportionally into a motor position for the actuator. In addition, an active analog position signal 4 ... 20mA is output. On request, analogue input signals from 2 ... 10V as well as 1 ... 5V are also possible.

Applicable function

• AutoScan: Automatically memorized each OPEN/CLOSE position by the signal of the potentiometer PIU.
• Fail CLOSE: Drives to CLOSE-position if there is no certain input signal.
• Fail OPEN: Drives to OPEN-position if there is no certain input signal.
• Fixed adjustment: It is possible to fix a certain signal as OPEN and CLOSE.

All NE-actuators have a solid and waterproof body, thermical overload protection and a heating device preventing condensation to ensure high durability.

All standard NE-actuators are equipped with 2 additional limit switches, manual override and an optical position indicator that is illuminated in OPEN or CLOSE position by LEDs. The optical position indicator protected under a glass cap on top of the body.

The actuator NE are equipped with mounting pad according to DIN ISO 5211 for a safe and functional mounting to industrial valves. A generously dimensioned output shaft ensures a secure transmission of the rotation torque to the valve. Two internal threads for cable glands enable electrical connection with separate cables for power supply and control.

In our shop, further variants of the electric actuator NE can be ordered online:

• Actuator with higher or lower torque. Up to 3.000Nm on request.
• Actuator with ATEX approval for using in explosive atmospheres.
• Failsafe actuator with spring return or SuperCap capacitors for safe operation into end position in case of power loss.
