STK- 8530 Electric Actuator
Product Description
The STK8530 is an intelligent multi-turn electric actuator from the Saltork family of actuators. Specifically designed to meet the most challenging valve automation demands of the Oil & Gas, Power, and Process industries, the STK8530 is compliant with a wide range of international standards and is the ideal solution to your plant’s safety and reliability requirements.
Non-intrusive with a user-friendly push-button panel for operation, configuration, and diagnostics
Bluetooth® wireless connectivity
Maintenance data includes full internal datalogger records, operating data, alarms, valve torque curves, and provides important information on the performance and operating condition of valves and systems
Configurable datalogger function for maintenance and diagnostic programs
Customized numeric and graphic displays with multiple language options
High-definition absolute encoder, able to read valve position even when main and backup power is lost
Contactless digital motor speed sensor
Wide range of advanced open-bus communication protocols:
Modbus®
HART®
PROFIBUS DPV0, DPV1, and redundant DPV2
FOUNDATION™ Fieldbus
LonWorks®
Watertight and explosion-proof PDAs available for remote control and setup
STKlink connectivity for monitoring, diagnostics, and setup. The Saltork STK8530 Modbus card is fully compatible with the Saltork standard configuration tool, allowing for operation of actuators in the field through the same interface
