Compact, spring-return electric actuators for industrial valve control. Watertight to IP67 with optional IP68 and explosion-proof variants. They offer torque up to 500 Nm (369 lbf.ft) and support AC/DC power. Key features include manual override, thermal protection, precise control, and communication protocol compatibility.
Features
• Spring-return electric actuator with watertight protection rated IP67 (optional IP68) and explosionproof variants
• Corrosion-resistant aluminium casing, treated and coated with TGIC-free polyester
• Self-locking gear system to prevent reverse rotation
• Manual override via a lockable handwheel for safe operation during power loss
• Thermal motor protection and internal heater to prevent overload and condensation
• Mechanical limit switches for precise valve positioning
• Speed controller to reduce shock during spring-return
• ISO 5211 compliant base with detachable drive bushing for flexible mounting
• Manual/automatic switching lever for control mode selection
• Optional extras include Local Control Units (LCU), Proportional Control Units (PCU), Current Position Transmitter (CPT), Emergency Action Unit (EAU), and various communication modules
• Supports Modbus, Profibus, Foundation Fieldbus, and HART protocols for seamless integration
