Spartan uses the Bettis - RTS electric actuator model series FL and FQ which utilizes a true mechanical spring return technology that is not reliant on the actuator motor or any battery backup to drive your valve to a true fail-safe position.

Fisher™ Easy Drive electric actuators can now help enhance your safety within your upstream control valve applications by adding Fisher’s super capacitor technology that allows your controls valve to go to a fail-open or fail-closed position.
