Product Description
1. Description
DCL explosion proof electric actuators are widely used in potential environment of flammable and explosive, such as petroleum, chemical, power plant, liquid gas, winery and metallurgy etc. To ensure workers are away from danger, explosion proof is a must. For different industries, zones and divisions, different explosion proof grade is required.
Actuators with ExdIICT4 and Group C, D T4 grade can be used in 90% explosive gas atmospheres except for colliery. The maximum surface temperature of actuator is less than 135℃ and 300.6F during severe duty applications. Over 10 years of safety operations in China, now all series anti explosion actuators have passed test process of CSA and been certified in 2022.

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)
