220V Electric Motor Operated Valve Actuators S2 Switch In Nuclear Power Plants ODM

DINKONDA GLOBAL Power Plants Special LZ Series S2 Switch Adjustable Type Intelligent Integrated Multi Turn Electric Valve Actuators

Product Overview

The LZ series valve electric actuator combines the electrical control part with the mechanical reduction mechanism, adopting a non-invasive design to form an integrated intelligent electric actuator. There are switch type and regulating type, which comply with the requirements of GB/T28270-2012.

This series of electric actuators is very convenient for users to install, debug, and maintain, which can greatly save installation costs, shorten installation cycles, and can be operated continuously on site, as well as remotely, centrally, and automatically controlled. The switch type is equipped with a control module that can output 4-20mA standard signals; The regulating type is equipped with an automatic adjustment module, which can accept and output 4-20mA standard signals, and can reliably control the opening of valves and achieve automatic adjustment.
