CHANGZHOU-SCHNEIDER (abr. as SND) non-intrusive intellectualized electric  modulating actuators
are products of new generation developed by cooperation on the basis of introducing the newest control
technology from Schneider.   

SND non-intrusive intellectualized electric modulating actuators consist of three ranges: linear type, multi-turn type and angular travel type (There are two structures for angular travel type: integral and
combined). They are suitable for industrial-process loop control systems and able to control gate valves,
globe valves, throttle valves, ball valves, butterfly valves and various modulating valves precisely.


These products are divided into two models depending on service environment: normal and explosion-proof.

Their general performance is conformed to the requirements of Standard JB/T 8219- Electrical Actuators
for Industrial-process Measurement and Control System. And the explosion-proof performance of
explosion-proof models is  onformed to the requirements of Standard GB 3836.1- 2000 Electrical
Apparatus for Explosive Gas Atmospheres–Part : General Requirements, and Standard GB 3836.2-
2000 Electrical Apparatus for Explosive Gas Atmospheres–Part : Flameproof Enclosure “d”.
