Auto Parts Diesel Injector Control Valve 621c for Common Rail Control Valve

Basf Chemical Co., LTDThe control valve plays an increasingly important role in the process industry and is an essential executive element to realize the automatic control of industrial enterprises. The selection of control valve under harsh conditions has always been the focus of instrument professionals and technicians in engineering design and operation and maintenance, and it is also the link that is prone to deviation in the selection of various instruments. In order to solve the problem of selection of control valves under harsh working conditions, a continuous production chemical plant of BASF Chemical Co., Ltd. is taken as an example. The working conditions of the device are harsh working conditions such as strong corrosion, high pressure, high temperature, etc. In some special working conditions, the selection of control valves exists cavitation and flash. In this paper, after analyzing the common types of control valves, combined with the actual selection cases to carry out a more in-depth study, and draw a conclusion on how to correctly select the control valve. It can not only provide an experience reference for instrument professionals, but also help to improve the production efficiency and safety of enterprises.

HControl valve plays an important role in process control, it is prone to failure in direct contact with the control medium, petrochemical and other enterprises will regularly maintain and maintain the control valve, instrument maintenance personnel need to have the ability to maintain the control valve. In order to realize the docking process of the learning process in the teaching implementation, combined with the main contents of the use, repair and maintenance of the control valve, according to the requirements of the national standard for the assembly and testing of the control valve, a pneumatic film control valve installation and adjustment training device is developed. The training device can complete the test of control valve assembly, positioner installation, stroke test, leakage test and other indicators during the maintenance of control valve and in the teaching process.
