Product Features：
Positioner: Controls the valve position based on control signals.
A positioner is a device used in control systems to control the final control valve, based on a control signal. It compares the actual position of a control valve to the desired position (the control signal) and sends the appropriate commands to the actuator to correct any differences.
In essence, a positioner ensures that the control valve opens, closes, or partially opens to the correct position in response to a control signal. This control signal is typically an electrical or pneumatic signal from a process controller.
Positioners are used in a variety of industries where precise control of fluid flow is necessary, such as in chemical processing, oil and gas production, and power generation. They are vital in these applications because they allow for more accurate control of the process, leading to increased efficiency and safety.

Under normal operating conditions. a safety factor of 20% - 30% is considered for double acting actuators
Example:
Valve torque= 100Nm
Safety torque- 100(1+ 30%) = 130Nm
Air source pressure=5Bar
Compared with the double-acting torque table, the specification of the optional Double-acting actuator is DA105.

Installation and Maintenance
Installation and Maintenance
The installation and maintenance of a Actuator are relatively straightforward. Here are some basic steps:
Installation: During the installation process, it’s important to ensure the actuator is correctly aligned and secured in the right position. The actuator should be properly interfaced with the driven device (such as a valve or other mechanical component) to ensure accurate and efficient operation.
Maintenance: Maintenance of the actuator typically involves regular inspections and replacement of worn parts. This might include replacing seals, cleaning and lubricating moving parts, and checking and adjusting the control system. In most cases, just carrying out these maintenance steps periodically can ensure long-term reliable operation of the actuator.
