How a valve fail-safe actuator works
A capacitor is installed into the actuator and discharges the stored energy to a motor, at this point the actuator is led to either a fully open or closed position. View our IACS blog post for any further information.
IACS' Sales Department is delighted to address any price or inventory-related questions you may have.
