STK-8750 Electro-Hydraulic Operator (Standard)
Product Description
The Saltork Standard Electro-Hydraulic Operator is a self-contained electro-hydraulic actuator designed to actuate quarter-turn valves. It is designed to provide fail-safe actuation for Emergency Shut Down(ESD) valves. The Saltork Standard provides a straight forward, simple, reliable ESD actuator solution.
Utilizes a dependable spring-return actuator for the fail-safe stroke combined with an integral hydraulic power pack and electronic control module
Designed as an emergency shutdown actuation solution to stop process flow upon the detection of a command signal or loss of power, protecting personnel, equipment, and the environment
Consistently operates in challenging environments, hostile environments, and when power is challenged
Over fifteen alerts and alarms to help alert users of abnormalities in the system
Can be integrated into systems with existing common communication protocols and STKLink
Communication Protocols- HART and FOUNDATION Fieldbus, STKlink configuration and monitoring software compatibility
Environmental Protection: Control enclosure: IP68, Hydraulic actuator: IP67M, Motor: IP68
