CHANGZHOU-CDF (abr. as SND) non-intrusive intellectualized electric modulating actuators are products of a new generation and designed with introduced technology from Schneider and developed by cooperation.

SND non-intrusive intellectualized electric modulating actuators consist of products 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 enable 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 conformed 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.
