What Are Electric Actuated Valves?
Electric actuated valves (also known as motorized valves) are the cornerstone of precise industrial flow control. By utilizing an electric motor to automatically open, close, or modulate the flow of liquids, gases, or steam, these devices eliminate the need for manual operation. Unlike pneumatic systems that require compressed air, electric valves offer highly accurate, remote-controlled automation—making them the ideal solution for complex and remote processing environments.
Engineered for seamless integration, Delco electric actuated valves deliver unparalleled reliability. Our robust solutions feature customizable torque ranges, diverse voltage options, and advanced position feedback signals to optimize your facility's efficiency.
To meet the precise demands of various applications—from water treatment to heavy-duty manufacturing—Delco offers a comprehensive portfolio of electric automated valves, featuring specialized valve bodies and actuator configurations:

| Fast, reliable 90° isolation for tight shut-off. Ideal for general water, HVAC, and industrial fluid control. | Cost-effective, high-capacity flow control. Engineered for quick operation in large pipelines and water distribution. | High continuous torque for multi-turn automation. Perfect for heavy-duty, high-pressure systems requiring unobstructed flow. | The ultimate solution for precise flow throttling and regulation in severe, high-frequency services. | Engineered with a sharpened blade to easily cut through viscous fluids, slurries, and wastewater for a secure seal. | ATEX/IECEx certified safety for highly flammable and hazardous environments (e.g., Oil & Gas, chemical plants). | Ultra-compact automation designed for tight installations and OEM equipment where space is critical. |
Why Choose Delco Electric Actuated Valves?
When you upgrade to Delco motorized valves, you aren't just buying hardware; you are investing in reliable, intelligent flow control. Trusted by engineers globally, our electric automation solutions eliminate manual errors and ensure seamless process integration under the most demanding conditions.
Precision Control & Smart Feedback
Our electric actuators provide highly accurate multi-turn or quarter-turn modulation. With built-in position feedback signals (e.g., 4-20mA), your control room always knows the exact status of your pipeline.
Built for Extreme Environments
Engineered with rugged, anti-corrosion housings. Whether you need standard weatherproof protection or ATEX-certified Explosion-Proof safety for hazardous areas, Delco delivers uncompromised durability.
Multi-Voltage & Easy Integration
Designed for ultimate flexibility. Delco electric valves support various power supplies (AC/DC) and feature standardized ISO 5211 mounting pads, ensuring quick installation without the need for custom brackets.
The Complete Automation Portfolio
From compact miniature valves for tight spaces to heavy-duty gate valves for high-pressure systems, we offer a "one-stop" solution tailored to your specific fluid control requirements.
Frequently Asked Questions (FAQ)
Q1: How do I select the right electric actuated valve for my application?
A: Proper sizing depends on four key factors:
-
The valve type and size (e.g., ball, butterfly, gate).
-
The maximum operating pressure and media temperature.
-
The required torque (we always include a safety factor).
-
Your available power supply (Voltage: AC or DC).
Contact our engineering team with these details, and we will provide a free, accurate sizing recommendation.
Q2: What happens to an electric valve if there is a power failure?
A: Standard electric actuators are designed to "fail in place" (they stay in their last position when power is lost). However, all Delco electric actuated valves come equipped with a manual override handwheel. This allows operators to safely open or close the valve by hand during an electrical outage.
Q3: Can these electric valves be used in outdoor or submersible environments?
A: Yes. Our standard electric actuators feature rugged weatherproof housings. For extreme outdoor conditions, flood-prone areas, or marine applications, we strongly recommend our IP68 Water-Proof Electric Actuated Valves, which are fully submersible.
Q4: Do you offer explosion-proof electric valves for hazardous areas?
A: Absolutely. For environments with flammable gases or combustible dust (such as Oil & Gas, petrochemical, or mining), we provide ATEX / IECEx certified Explosion-Proof Electric Actuated Valves. These units ensure safe, spark-free operation in highly hazardous zones.
Q5: What control options are available for your motorized valves?
A: We offer two main control types to suit your automation needs:
-
On/Off (Open/Close): Provides simple, full-travel operation for isolating flow.
-
Modulating (Proportional Control): Accepts standard input signals (like 4-20mA or 0-10V) to continuously adjust the valve position for precise flow regulation.
