PWS-770-CHDC00E Application Field and Working Principle

The PWS-770-CHDC00E is an electrically operated quarter-turn actuator which is designed for continuous power operation and non-fail-safe shutdown processes. It is suitable for both electrical installation systems and plant maintenance, and can be used to control valves/valves in hazardous or corrosive environments. The PWS-770-CHDC00E is an ideal choice for applications such as chemical-processing, power generation, process control, wastewater treatment, and other industrial applications.

Accessories

The PWS-770-CHDC00E comes with unique accessories such as an integral servo motor that offers low starting torque and high start voltage. The motor is specially designed and sealed to protect it from harsh environmental conditions, such as salt spray and extreme temperatures. Other accessories included are on/off fault indication, manual/automatic override switch, and electronic monitoring and protection of the actuator. The monitoring features include temperature and current sensor, indicating the actuator’s location and status. The actuator also has various status signals that will indicate when the position of the actuator reaches at its limit.

Working Principle

The working principle of the PWS-770-CHDC00E is simple and efficient. It consists of a servo motor and a coupling system which is connected to the valve/valve positioner. The servo motor works in both directions, either in clockwise or counterclockwise, to open or close the valve/valve positioner according to the command signal. Its operation is accomplished by the transmission of electrical current from the motor to the actuator, which causes the motor to rotate the actuator. This rotation is monitored and controlled by an internal system, and when the rotation is completed, the electronic command signal is terminated and the valve/valve positioner is in its desired position.

The PWS-770-CHDC00E is designed with several features to ensure reliable and efficient operation. Its internal system is designed to prevent against external forces and any sudden load that may damage the motor or the actuator. It is also designed to detect any abnormal situation that could arise during its operation, such as low voltage or overheating. Additionally, the actuator is designed to provide troubleshooting features to identify and rectify faults.

The PWS-770-CHDC00E is an ideal choice for applications that require reliable, efficient, and safe valve control and operation. Its unique design, built-in protection system, and wide range of accessories make it a great choice for industrial and hazardous environments. It is an efficient, cost-effective, and reliable solution to many different applications.
