• Torque range: 40–3000 N.m
• Control & feedback: digital, 4–20 mA, M-bus, P-bus, FF
• Certifications: CCC, ExdIIBT4, ExdIICT6, IP66/IP71, EAC, SIL, CCS

CKDJII Part-turn Smart Series

• Models: CKDJII20, CKDJII50, CKDJII100, CKDJIII250, CKDJIII300, CKDJIII500
• Torque range: 100–1500 N.m
• Output angle: 0–90°
• Control & feedback: digital, 4–20 mA, M-bus, P-bus, FF
• Certifications: CCC, ExdIIBT4, ExdIICT6, IP66/IP68, EAC, SIL, CE, ATEX, CCS

The CKDJII electrical design builds on the CKDII intelligent platform with a clean, compact structure. The absolute encoder retains valve position without batteries; M-bus/P-bus fieldbuses and FF suit smart water and smart plant scenarios.
