DELCO QT Series Explosion-Proof Electric Actuator - Certified Safety & Wide Angle (0°-270°) Control
The DELCO QT Series Explosion-Proof Electric Actuator is engineered for reliable automation in hazardous industrial sectors such as petroleum, chemical engineering, and power generation.1 Fully certified for explosion-proof safety, this actuator ensures guaranteed quality and operational integrity in dangerous environments.2 It distinguishes itself with a versatile rotational range of 0° to 270°, enabling control over diverse equipment like ball valves, butterfly valves, air throttles, and dampers.5 Driven by standard AC power supplies (380V/220V/110V) and controlled via 4-20mA or 0-10VDC signals, it delivers precise positioning with a maximum torque of up to 2,000 N.m.
Features
A certified explosion-proof electric actuator from the DELCO QT Series, offering up to 2,000 N.m torque and a wide 0° to 270° rotational range for safe, precise valve automation in hazardous environments.
✅Certified Explosion-Proof Safety: The product has passed rigorous explosion-proof certification, providing guaranteed quality and safety assurance for operation in hazardous zones containing flammable gases or dusts (e.g., petroleum and chemical industries).
✅Wide Rotational Range (0°-270°):Unlike standard quarter-turn actuators, the QT Series supports rotation from 0° up to 270°, making it highly versatile for controlling not just standard valves but also air throttles, baffle valves, and shutter valves.
✅High Torque Capability: Delivers a powerful maximum output torque of 2,000 N.m, ensuring sufficient force to reliably operate and seal medium-to-large valves even under high-pressure conditions.
✅Precise Proportional Control: Utilizes standard analog control signals (4-20mA current or 0-10V DC voltage) to move the valve to the exact required position, enabling fine-tuned automated flow and pressure control.
✅Broad Industrial Versatility: Designed for widespread application across critical sectors including heat supply, shipbuilding, water treatment, paper manufacturing, and building automation, compatible with various multi-voltage power sources.
