HM Series (HKC Multi-turn)
The HM Series, electric multi-turn actuator, is designed for multi-turn valve applications, such as globe valve. In combination with a gearbox, it is also used for large size quarter-turn valves, such as ball and butterfly valves.
• A wide LCD window provides various useful information such as valve position and torque.
• Easy setup using a remote control.
• Partial stroke function for valve diagnosis and water hammer prevention function are included as standard.
• Precise modulating control (500:1 based on 1 minute operating time) as an option.
• Flameproof (Ex db IIB +H2 T4) as an option.
• IP68 (upto 10 m, 72 hours) as an option.
• Communication (PROFIBUS, MODBUS) options.
