Explosion proof electric actuator for Zone 1 & Division 1 0-360° adjustable

• Turning angle ≤360° adjustable with electric limit switches
• Explosion proof grade ExdIICT4 for Zone system and Group C, D T4 for Division system
• Stainless steel visual valve position indicator with 10mm tempered glass lens
• Hard die cast aluminum alloy enclosure to resistance to high explosive pressure inside
• Heavy duty fully enclosed squirrel-cage asynchronous motor with fire treatment
• Manual override with Allen handle/handwheel optional
• Double lip skeleton oil seal and O-ring seal to ensure protection grade to IP68
• Standard ISO 5211 direct mounting
• Update:The DC12V power supply models DCL-Ex05, DCL-Ex10 and DCL-Ex20 have obtained CSA certification.

The entire line of DCL explosion-proof electric actuators is now proudly CSA-certified.

Designed for maximum versatility, the DCL-Ex10 model features an adjustable rotation angle of up to 360°, making it the ideal solution for hazardous environments exposed to flammable and explosive gases like ethylene and ethanol.

Precision Engineered for Ultimate Safety To guarantee uncompromising explosion-proof performance, the flameproof joints between the housing covers and cylinder stops are machined to perfection. We don't just meet strict UL standards for gap dimensions and engagement lengths—we exceed them. Because precision is critical, DCL enforces internal dimensional tolerances that are even tighter than UL requirements, backed by comprehensive, 100% inspections of all actuator bodies and covers prior to assembly.

Advanced Thermal Control At the heart of the DCL-Ex10 is a custom-engineered, fully enclosed, non-ventilated motor that delivers exceptional starting torque. Despite its ultra-compact design, the actuator features superior heat dissipation. This effectively manages internal temperatures during heavy-load operations, ensuring the outer shell never exceeds 135°C (275°F) and completely eliminating external ignition risks.
