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.
