Intrusive Multi-Turn Actuators - SMB

• Long service life with rugged with cast iron housing and precision-machined gearing
• Extreme environment performance enabled by nuclear, weatherproof, submersibleor explosion-proof construction
• Lower maintenance and downtime owing to torque-limiting feature, which de-energizes the motor to prevent valve damage in the event of an obstruction
• Fully qualified for nuclear applications to IEEE 384, 323 and 344
