Description

DCL-Ex05 explosion electric actuator can set turning angle up to one full round. Actuators are widely used in environment with explosive gas, such as Ethylene, Ether, Ethanol etc. Cylinder stop type connection surface of each housing cover complied to UL standard flame proof gap and length. The processing quality of flame proof surface is the key process to ensure explosion grade, so the machining tolerance range must be smaller than UL standard requirements. Thus, every explosion body or cover from supplier is strictly tested by DCL before assembling.

DCL actuators use self-designed motors that is non-ventilated and full enclosed with high start torque. Due to the very compact size of actuator, the temperature rise of motor must not be high during heavy duty operation, to make sure the outer shell’s temperature will not go beyond 135℃ or 300.6F.

Specification

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)
