What Are Electric Actuated Valves?
Electric actuated valves use an electric motor to open, close, or modulate the flow of liquids, gases, or steam. Unlike manual or pneumatic options, they allow remote operation and precise control, making them ideal for modern process automation. With customizable torque ranges, voltage options, and feedback signals, Delco electric actuated valves deliver both reliability and flexibility across industries.
Delco offers a complete portfolio of electric actuated valves, covering different valve bodies and actuator configurations:

|
| Compact, tight-sealing solutions for water, gas, and oil pipelines. | Lightweight, cost-effective for large-diameter pipelines and HVAC systems. | Robust shut-off for high-flow applications. | Designed for throttling and precise flow regulation. | Reliable operation for slurry and solid-laden fluids. | ATEX-certified solutions for hazardous environments. |
Key Features & Advantages
When selecting electric actuated valves, Delco provides:
Corrosion-Resistant Solutions
PTFE, PFA lined options & special alloys (Hastelloy, Monel) available for aggressive chemical media.
Seamless System Integration
Compatible with major DCS/PLC systems via Modbus, Profibus, or 4-20mA signals. Pre-wired & tested.
Universal ISO 5211 Mounting
Direct mounting capabilities for easy actuator retrofitting and maintenance without brackets.
Fail-Safe Protection
Optional battery backup or spring return ensures safe valve position (Open/Close) during power loss.
