Anwochi Aventics Control Valve

Anwochi Aventics regulating valve, also known as control valve, changes fluid flow rate by receiving control signals output by the regulating control unit and using power operation. A regulating valve is generally composed of an actuator and a valve. If the power used by the actuator is used, the regulating valve can be divided into three types: pneumatic regulating valve, electric regulating valve, and hydraulic regulating valve. In addition, according to its function and characteristics, it can be divided into three types: linear characteristic, equal percentage characteristic, and parabolic characteristic.

Regular calibration of Aventics regulating valve by Anwochi

Units that have not yet carried out predictive maintenance work for regulating valves should conduct regular calibration of regulating valves. Regular verification work is preventive maintenance work.

According to different production processes, the regular calibration of regulating valves should have different calibration cycles. The periodic calibration cycle for each regulating valve can be determined based on the information provided by the manufacturer. Usually, it can be carried out simultaneously with major repairs during the production process. When some regulating valves are used in high-pressure, high-pressure drop, or highly corrosive environments, the inspection cycle should be shortened.

The main content of the inspection is the static performance testing of the regulating valve, and if necessary, corresponding testing items can be added, such as testing the flow characteristics of the regulating valve. Regular calibration requires testing equipment and instruments, as well as replacement parts, so it can usually be entrusted to the manufacturer for completion.

Anwochi Aventics Control Valve Maintenance

The maintenance of regulating valves includes emergency maintenance, regular maintenance, and predictive maintenance. Emergency maintenance refers to the repair when the regulating valve malfunctions and cannot meet the requirements of the process operation. Regular maintenance usually includes routine maintenance and maintenance carried out simultaneously with process shutdown overhaul. Proactive maintenance is the targeted repair of regulating valve components based on the analysis results of proactive maintenance. Emergency maintenance refers to the repair after the failure of the regulating valve, while regular maintenance and predictive maintenance refer to the repair before the failure of the regulating valve. Usually, the daily maintenance of regulating valves is carried out by instrument maintenance personnel, while regular maintenance carried out simultaneously with major repairs is carried out by manufacturing technicians.
