Metryva MTVM8 Series Electric Actuators
The MTVM8 Series (MTVM8300/MTVM8400) are intelligent multi-turn electric actuators designed for use with valves, dampers, and similar control equipment. They utilize a durable worm and worm-gear drive mechanism that provides mechanical self-locking when power is removed, ensuring stable positioning and safety.
These actuators feature a digital LCD display with Chinese or English interface for convenient configuration, monitoring, and diagnostics. They support multiple control modes including digital inputs and analog (4-20 mA) signals, enabling both local and remote operation.
Built for harsh industrial environments, the M8 Series offers an IP68 protection rating (higher available in some variants) and operates reliably within ambient temperatures of –25 °C to +70 °C. A manual override hand-wheel allows mechanical operation in case of power loss.
