The Group 57 valve actuators are a great choice for valve actuation in remote, hazardous environments. In addition to running on AC power, the group 57 units are also DC powered electric actuators, explosion proof and therefore perfect for situations where explosive gases are present. These valve actuators reset to a fail-safe position during power outages and are great for low power environments such as a gas pipeline using solar power, batteries and fuel cells. Built with your need for flexibility in mind, Beck reliability standards and a rugged construction design for harsh environments.
