• Brushless, robust DC motors ensure reliable operation regardless of load.
• The valve actuators do not require an end position switch, are overload proof, and remain in place upon reaching the end stop.
• The gears are maintenance free and low noise.
• Suitable for use with modulating (DC 0…10 V), 2-position or 3-position controllers.
• We recommend a minimum pulse length of 500 ms on rotary actuators operated with 3-point control to ensure continuous and accurate operation.
• On plants where the rotary actuator must move to the zero position (emergency position) during power failure.
