Exdiict4 Modulating Ex-Proof Electric Actuator for Ball Valve, Butterfly Valve, Gas Valve, Self-Locking, IP68
Description
DCL modulating type explosion proof electric actuators are
self-designed with patent, that is very compact size with resin
plastic packaged control pack inside.
DCL is continuously improving the Electro-magnetic Compatibility
(EMC) of actuator. DCL built a dedicated testing laboratory with
comprehensive devices for over 10 years. We insist to do below
tests before butch production to ensure our products with stable
quality.
For supplier quality control, we do 100% machining precise tests of
cabinet to ensure every flameproof gap and length can meet ATEX and
UL standard.
During assembling, we do below tests for 100% of our products.
DCL regards quality as life. All above tests are guarantees of stable quality.

Control Circuit of Type E
The Servo-controller is located inside of the actuator. It receives
command of the central control system and drives valve to proper
opening position according to varying conditions of
variables(flow,pressure,temperature,fluid level) in the pipe.
Adopt character of service of S4 intermittent type, working
frequency reaches 1200 times/hour.
Servo-Controller
The unique circuit design, imported technical grade electronic
parts and components and modern making technology of circuit board
of the DCL ensures high quality and reliability of the
servo-controller. The circuit board with resin plastic package
makes shock and humidity resistance better.the unique electronic
brake function makes actuator dead-beat when position is fixed, the
period of damping character is zero times(standard: Less than 3.5
times)
