Specifications of TCR-N electric actuators The TCR-N range is available with torque values from 15 Nm to 400 Nm and supports three different voltages: 95-265V AC/DC , 24V AC/DC , and 12V DC . The TCR-N electric actuators feature a compact design with a 90° operating angle (±2°). They include an ISO 5211 pad and star connection . The ABS plastic enclosure and steel reducing box ensure durability and efficiency. They operate in temperatures from -20°C to +60°C . Duty cycle is S4 (50% operational time), except for TCR20 and TCR40 models which have an S3 duty cycle (85% operational time). Focus on the on-off function The TCR-N electric actuators are designed for On/Off control of ¼ turn valves , providing precise and reliable valve actuation. These actuators are ideal for applications involving ball and butterfly valves due to their compact construction and their 90° operating angle.. On/Off functionality refers to the capability of the actuator to fully open or fully close a valve. This binary operation is essential in many industrial processes where valves need to be either completely open to allow full flow or completely closed to stop the flow. The On/Off mode ensures that there is no partial opening or closing. Standard equipment of TCR electric actuators The TCR electric actuators come with adjustable limit switches and 2 auxiliary limit switches. They feature thermal protection , a 3D position indicator , a manual override by hex key, and regulated 2-3 W anti-condensation resistor. These actuators are equipped with an IP67 leak-tightness rating, making them suitable for indoor use and potentially for outdoor use under proper shelter. ans-serif"> parallel installation, the TCR-N actuators allow multiple units to operate simultaneously, which is crucial for systems requiring synchronized valve movements. Additionally, they offer manual control with a key, providing a necessary override option for maintenance or in case of power failure.
