Abstract: DYL electro-hydraulically controlled cold wall slide valve is widely used in heavy oil catalytic cracking unit to control the amount of catalyst circulation. It is mainly made up of 3 parts: valve body, manual mechanism and electro-hydraulic actuators. A series of innovative structural designs are applied to the device, including the new internal structure of rail bolt anti-fracture, “intelligent” electrohydraulic actuator, the design and manufacture of large diameter slide valve, single packing gland seal structure, etc. By introducing advanced application technology, and developing and utilizing special slide valve design software, the quality of slide valves has been improved, and prolonged their service lives. The service lives of the components were extended by 3-5 years, the maintenance cycle shortened by 1/4 - 1/3, which guarantee the safety of refining devices. The product is reliable in quality, environment friendly and convenient to operate. The control precision index has reached the domestic leading level.
