STK-8510 Electric Actuator
Product Description
The STK8510 is an intelligent quarter-turn electric actuator from the Saltork family of actuators. Compact and lightweight, this all-in-one actuator fits all the features of larger, heavier actuators into a neat, innovative design. Deploy the STK8510 to maintain effective control of low-torque, quarter-turn valves and dampers in even the largest and most complex plants.
Separate terminal enclosure is kept isolated from the electronics and motor compartment; only the wiring terminal is exposed during field installation
Standard adjustable torque switches, from 50 to 100% of rated torque output (3 steps: 50% - 75% - 100%)
Manual override is always engaged
Anodized aluminum with epoxy powder coat to protect unit against the decaying effects of aggressive environments
Visual mechanical position indicator for accurate visual reference of valve position
Directly mountable or readily adaptable to other quarter-turn valves
Permanently-lubricated, self-locking gear train helps eliminate the need for motor brakes; Epicyclical gearing ensures reliable and smooth operation
Mechanical travel stops designed to prevent over-travel during hand wheel or motor operation
Over-temperature motor thermostat
Integral speed control, independently adjustable in opening and closing directions
Latched-type output contacts for fully open / fully closed remote indication. Output contacts for monitor and blinker/local selector indication are also available
Optional modules add even more functionality and intelligence:
OM1 – Modulating Input/Output module
OM3 – Local Interface module
OM9 – PROFIBUS DP V0/V1 bus communication
OM11 – DeviceNet bus communication
OM13 – 3-wire module
