The actuators NE with ATEX approval can be used as an efficient 90 ° electric actuator for the actuation of butterfly valves and ball valves in OPEN-CLOSE operation in explosive atmospheres zone 1, in which occasionally flammable gases or vapors may occur. The self-locking worm gear ensures precise positioning.

All NE-actuators have a solid and waterproof body, thermical overload protection (only 230V AC) and a heating device preventing condensation to ensure high durability. In addition, all actuator with a torque of 150Nm and above have special torque switches for OPEN and CLOSE rotation direction to prevent against overload.

All standard NE-actuators are equipped with 2 additional limit switches, an optical position indicator and a manual override by means of a hand wheel, which is disengaged in normal operation and does not rotate. The optical position indicator protected under a glass cap on top of the body. Especially for the high requirements in explosive atmospheres, all construction-related body openings are especially sealed.

Because of these characteristics this actuator will be suited for demanding tasks, e.g. in:

Energy

• Power plants
• Air pollution control
• District heating
• Pipelines

Chemical industry

• Chemical industry
• Petrochemical industry
• Pharmaceutical industry

Water/Wastewater

• Water works
• Sewage treatment plants
• Pumping stations

Others

• Oil- and gas industry
• Air conditioning
• Ship building industry
• Steel mills
• Cement plants
• Foot industry

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.
• Actuators with PCU board for positioning operation with analog signal 4…20mA or 0…10V.
• Failsafe actuator with spring return or SuperCap capacitors for safe operation into end position in case of power loss.
