Arctic-Level Challenge: Mikenson DG Series Pneumatic Actuator, Unwaveringly Stable in Extreme Cold

Many people ask: just how cold is the North Pole?

Ice drift observations near the North Pole have recorded extremely low temperatures of approximately −59°C. This goes beyond ordinary “cold”; it is an environment that pushes materials to their performance limits and mechanical systems to their operational extremes.

Chengdu Mikenson Flow Controls MFG. Co., Ltd has designed its DG Series pneumatic actuator precisely for such extreme conditions—with the entire unit engineered to withstand frigid operations down to -60°C.

This means that whether at a long-distance pipeline site in Russia's high-altitude cold regions or on the icy docks of a National Pipeline Network LNG terminal, when low temperatures begin to impair lubrication, contract materials, and amplify structural resistance, the DG Series continues to respond accurately and perform reliably.

This capability stems from four core technologies of the DG Series:

• Dual-Guide Scotch Yoke Structure – Enhanced balance and eccentric load resistance

The main drive housing features a globally unique dual-guide scotch yoke design. By incorporating bidirectional constraints and balanced force distribution, it delivers more stable output torque transmission, reduces eccentric loading and localized wear, and improves long-term operational reliability.

• 600,000 N·m High Torque Output – Drives large-diameter ball valves

With a maximum output torque of up to 600,000 N·m, the DG Series meets the drive requirements of ultra-large-diameter and high-load ball valves while maintaining motion continuity and control consistency under high-torque conditions.

• -60°C Extreme-Cold Design – Optimized to mitigate low-temperature failure risks

The entire actuator reliably withstands extreme -60°C conditions, with structural and material optimizations addressing reduced lubrication performance, material contraction, and increased running resistance—ensuring dependable operation in low-temperature environments.

• Comprehensive Safety Certification System – Covers complex and harsh conditions

Respect for extreme conditions is not just a slogan—it means defining extreme boundaries during the design phase.

Mikenson DG Series answers this with SIL3 certification, defining safety redundancy levels at the system level. Additionally, ATEX explosion-proof certification and IP66/IP67 ingress protection ratings ensure reliability in flammable, explosive, water-exposed, and outdoor harsh environments.

Together, this triple certification means that even when multiple adverse conditions—low temperature, explosion risk, water exposure—coincide at a site, the DG Series still delivers third-party-verified safety and protection.

The cold of the Arctic is a fact; Mikenson DG Series is the preparation. And Chengdu Mikenson’s vision is this: when extreme conditions arrive, Intelligent Manufacturing in China provides the most reliable answer.
