DK-EXS-CT6 Electric Actuator - IIC T6 Explosion-Proof for Hydrogen/Acetylene | DELCO

✅Ultimate IIC T6 Explosion Protection
Unlike standard IIB actuators, the CT6 model is tested to suppress internal explosions of high-energy gases like Hydrogen and Carbon Disulfide. It meets strict GB3836/IEC60079 requirements for Zone 1 & 2, ensuring maximum plant safety.
✅Double-Sealed IP68 Watertight Design
The unit utilizes a dual-sealing structure. Even if the terminal box cover is removed for wiring during rain, the internal motor and electronics remain isolated and protected. Rated IP68, it withstands continuous underwater operation (up to 10m depth/72h optionally).
✅Non-Intrusive Commissioning (Infrared)
Operators can configure torque limits, position limits, and control modes using an Infrared Remote Setter. This "Non-Intrusive" technology means the explosion-proof cover never needs to be opened on-site, preserving the seal integrity and protecting internal components from moisture and dust.
✅Comprehensive Self-Diagnosis & Protection
The integrated smart CPU continuously monitors operational status. It provides alarms for phase loss, over-torque, motor overheating, and signal loss. In case of signal failure, the actuator can be set to fail-safe positions (Open/Close/Stay Put) to protect the pipeline process.
✅Wide Specification Coverage (50-3000Nm)
From compact EX05 units to heavy-duty EX300 models, the series delivers reliable torque for ball, butterfly, and plug valves. High-efficiency worm gearing ensures self-locking functionality, preventing valve back-drive even under fluctuating flow pressures.
