Maintenance and repair to the normal operation of the control valve

Control valve as part of the automated control system, its maintenance and automation, instrumentation and other equipment at the same time.angle seat valves
Control valve similar to the maintenance and general maintenance of the instrument can be divided into passive maintenance, preventive maintenance and predictive maintenance. The passive maintenance is carried out only when the control valves and other equipment failure maintenance of a maintenance method. Because of equipment failure, maintenance of parking, often resulting in the production process, even when serious equipment damage or casualties. Passive maintenance production process do not want to maintenance, preventive maintenance is based on past operating experience, by the time the maintenance of a maintenance method. For example, commonly used regular maintenance is preventive maintenance, according to the operation of equipment to develop appropriate maintenance schedule, in maintenance equipment failure. Due to a failure does not occur on maintenance, and therefore, can greatly reduce the probability of occurrence of failure. This is maintenance does not currently use the control valve for analysis, disassembly and inspection often control valve can also use a certain period of time, a waste of time and resources. Predictive maintenance control valve data from the current analysis, we foresee that the state of the control valve, so that the control valve to maximize the utilization.high temperature solenoid valve
