"E-Series" Electric Actuator
The Nextek "E" Series Electric Actuators are high-performance rotary actuators designed for precision control in industrial applications. These actuators are ideal for automating rotary valves, such as ball, plug, and butterfly valves, and are built to excel in environments where compressed air actuation is impractical. Nextek's "E" Series offers robust features, including NEMA 4 and NEMA 7 enclosures for weatherproof and hazardous location operation. Whether you need precise control or multi-position actuation, the "E" Series delivers consistent, reliable performance.
- Heavy-Duty Motors: The "E" Series actuators feature powerful motors designed for both On/Off and modulating services, making them suitable for various applications, from simple valve control to complex flow regulation.
- NEMA 4 and NEMA 7 Enclosures: These actuators are available with NEMA 4 (weatherproof) and NEMA 7 (hazardous location) enclosures, ensuring optimal performance in demanding environments.
- Reversible Motors: The actuators utilize reversible motors that provide precise control by reversing the motor without completing a full stroke. This is ideal for applications requiring fine adjustments in flow.
- Manual Override: Every model includes a manual override feature, giving users complete control in case of power loss or emergencies.
- Corrosion-Resistant Coating: The thermally bonded polyester coating ensures long-lasting durability in corrosive environments, extending the actuator's life.
- Wide Operating Temperature Range: The actuators are built to operate in extreme temperatures, ranging from -40°F to 150°F, making them suitable for use in various climate conditions.
- Permanently Lubricated Gear Train: The enclosed, hardened steel gear train is permanently lubricated, reducing the need for regular maintenance and ensuring smooth operation over time.
The Nextek "E" Series actuators are perfect for:
- Valve Automation: Control rotary valves like ball, plug, and butterfly valves.
- Sub-Freezing Operations: When fitted with a heater, the actuators are ideal for temperatures dropping below freezing.
- Multi-Position Actuation: Capable of providing three or four distinct stop positions, making them ideal for multi-ported valves and other complex applications.
- Heater & Thermostat: Maintain optimal actuator performance in cold or humid environments.
- Electromechanical Brake: Prevents oscillation during butterfly valve seating.
- Auxiliary Switches: Additional limit switches can be added to interlock with equipment like pumps or mixers.
- Analog Positioner: Supports 4-20 mA input for precise positioning applications.
- Torque Sensor Control protects the actuator from damage caused by unexpected increases in torque caused by valve wear or pipeline obstructions.
