Product Description

1. Description

DCL-40 series electric actuator uses power-to-open and power-to-close, stays in last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a rugged all metal gear drive rotates the output drive 90°. The motor is automatically stopped by internal cams striking limit switches. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the output drive position.

The Series DCL-40 actuator is designed to be space efficient, and easy to install package possible. The compact enclosure minimizes interference problems common in modern piping and control rooms.The actuator base conforms to international standards, and female drive allows the direct mounting on most valves without expensive and space hogging custom brackets.

On-off Type Actuator

Control circuit of type A/B/D/G/H

On-off type has only full-open and full-close limit positions.You can preset middle position(typeB/G/H) if you need.

Actuator will drive valve to full-open or full-close or middle position etc.when receiving proper command.

Adopt the S2 short-time duty, the time of continuous operate less than 15 minutes.


Feedback Type Actuator

Control circuit of Type C/D/F

During the actuator drives valve, it will full-range feedback valve signal to central control system at the same time.

Type C/D feedbacks valve signal of resistance quantity, type F feedbacks valve signal f analog quantity.

Adopt the S2 short-time duty, the time of continuous operate less than 15 minutes.


Adjusting Type Actuator

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.
