The MO 3 multi-turn electric actuator is designed to handle demanding tasks in automated valve control within industrial systems, where high performance, durability, and reliable functionality are essential even under repeated loads. Its technical parameters and construction make it an ideal solution for operating gate valves, knife gate valves, wedge gate valves, soft-sealing valves or metal-to-metal sealing applications. It is commonly used in sectors such as energy, water management, chemical and gas industries. The robust aluminum housing ensures high mechanical resistance, and its IP67 rating guarantees flawless operation, even in extreme outdoor environments.

The MO 3 actuator is engineered with emphasis on control accuracy, long service life, and easy integration into existing control systems. It supports both manual and remote control, and can be optionally equipped with position feedback and other features depending on customer needs. Thanks to its flexibility in configuration and mechanical connection, consistent performance, and reliability, the MO 3 represents an intelligent choice for modern industrial applications, where safety, efficiency, and long-term operational reliability come first.
