Adjustment method
regulating type
The servo controller is placed inside the actuator and receives commands from the central control system to drive the valve to the appropriate opening position based on changes in the controlled variables in the pipeline (flow, pressure, temperature, level).
Adopting S4 intermittent type working system, the working frequency is up to 1200 times per hour.
switching type
A, B, G type control circuits
Switching models have only fully open and fully closed limit positions; intermediate positions can be preset if desired (B, G models). Upon receipt of a command, the actuator will drive the valve to the fully open, fully closed, or intermediate position.
The S2 short-time type working system is adopted, and the continuous running time does not exceed 15 minutes.
Functional Features
electrical machinery
Due to the working characteristics of the valve, the actuator is required to have the ability to start at full load in the opening, closing and any intermediate position of the valve, which requires the motor of the actuator to have a high starting torque. This requires the actuator motor to have a high starting torque, and at the same time, due to the need for opening adjustment, the motor is required to have a small moment of inertia.DCL series electric actuator motors are specially designed to meet these requirements.
When the actuator is blocked, the temperature of the motor will rise rapidly. When the motor temperature rises to 125°C, a PTC thermal protector placed in the motor windings cuts the circuit to protect the motor and the control system. When the motor temperature drops to 90-105℃ whenThe circuit will come back on.
Electrical and mechanical limits
Electrical travel limit function: When the actuator reaches the fully open or fully closed limit position or the set intermediate position, the built-in electrical limit switch will cut off the circuit to protect the actuator.
Output Shaft Mechanical Limit Function: When the electrical travel limit function fails, the output shaft of the actuator will be locked by the mechanical limit device, thus protecting the valve from damage.
The diagram shows the positional relationship between the electrical and mechanical limits.
