Detail: IP68 non-intrusive intellectualized electric modulating
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 AtmospheresPart : General Requirements,
and Standard GB 3836.2-
2000 Electrical Apparatus for Explosive Gas AtmospheresPart :
Flameproof Enclosure d.
