VTM Series Electric Actuator
The VTM Series Electric Actuator features a compact size, robust construction, lightweight, and a large output torque (35NM – 4000NM). Worm gearing and vortex rod in high precision provide self-locking function and declutchable manual override design that eliminates clutching operation in operation method switch. The series offers product features guaranteeing a stable and convenient operation satisfying IP67 protection level and ISO5211 mounting standard.
The VTM Series Intelligent Electric Actuator is an intelligently controlled actuator. It combines a multi-function server amplifier and a position signal transmitter.
It is not equipped with adjustable parts. All settings can be set by the infrared remote control, such as on -site debugging, sensitivity settings, manual automatic switching and other functions. The LCD display control panel will show the current working status of the product.
A control box is installed on the product will receive standard 4-20 m A current control or on-off control signals from DCS control system or other upper computer control system and convert them into valve action parameters.
