|Electric Actuators from RENCOR|
The ProMation Engineering actuators feature a self-locking hardened steel drive train for smooth operation, mechanical end of travel stops, and patented clutch-free manual override for single-handed positioning of the actuator in any situation.
Some models include an integrated position indicator, two auxiliary switches, an internal low-power anti-condensation heater, and cast aluminum polymer coated housing. Using two 3/4" conduit connections, the actuators are rated NEMA 4X for safe exposure to high pressure hosing and corrosion resistance.
Proportional control units accept a wide range of control signals while generating multiple feedback signals and are easily installed, calibrated, and adjusted in the field.
The actuators are available for 24 VAC/VDC, 120/230 VAC or single phase and complete 3-Phase offerings. They are ISO 5211 compliant, conform to AWWA C540 standards, are certified to CSA 22.2 standards including ANSI/UL 50 and ANSI/UL 429, and are ARRA compliant.
Available options include torque switches, motor control centers, phase monitors, potentiometers, cold weather kits (for operation to -40 degrees F/C), timers, speed controls, single wire control interfaces, a wide array of feedback control interfaces, local control units, and fail safe solutions. All options are factory installed, calibrated, and tested.
