Electric Actuators
Electric actuators offer a compact, efficient design with minimal environmental impact. Used to control pressures by remotely opening and closing pipeline valves, the deployment of electric actuators continues to increase in upstream, midstream and downstream oil and gas applications.
Forum’s ABZ™ product line includes electric actuators for valve applications. Built to withstand harsh drilling environments, they feature watertight, explosion-proof enclosures, built-in stall protection and certified operating temperatures between -20 to 300 degrees Fahrenheit.* By providing superior drilling well shutoff control, they offer added protection for personnel, equipment and the environment.
All of Forum’s ABZ actuators and valves meet strict specifications such as the National Electrical Manufacturers Association (NEMA), International Protection Marking (IP) and the Canadian Standards Association (CSA).
