Explosion proof electro-hydraulic linkage ball valve is currently an advanced pipeline control equipment used to control valves both domestically and internationally. It is mainly installed in chemical, power, energy and other pipelines, serving as a shut-off and check valve. When working, the valve cooperates with the pipeline host, and according to the principle of fluid dynamics transition process, through the preset opening and closing program, effectively eliminates the pressure fluctuation of the pipeline medium, achieves reliable shut-off of the pipeline, and plays a role in protecting the safety of the pipeline system. The explosion-proof electro-hydraulic linkage actuator produced by our company has a high degree of automation, complete functions, stable and reliable performance. It is a new generation of intelligent, efficient and energy-saving products independently developed by our designers by introducing multiple research results such as valves, hydraulic, electrical, intelligent control, etc. The company has strong technical strength and can independently design according to the special requirements of users, meeting the needs of a wide range of users for this type of product from multiple perspectives. The main features of this product are as follows: 1. Can replace conventional electric actuators and integrate mechanical, electrical, and hydraulic systems into a whole, reducing footprint and infrastructure investment. 2. The electro-hydraulic control function is complete, and it can be used as an independent system for on-site debugging and control without the need for additional configuration; It can also be used as a device unit in a distributed control system (DCS), centrally managed by a central computer through I/O channels, and operated in conjunction with water pumps and other pipeline equipment; And equipped with manual function, it can also manually open and close valves without power supply, meeting the requirements of valve debugging and control under special working conditions. 3. Good controllability, large adjustment range, large output torque, stable operation, and strong adaptability. The explosion-proof electro-hydraulic linkage ball valve electro-hydraulic control system is designed according to customer requirements, which can meet different pipeline control functions and can be pre-set with opening and closing programs to ensure that when the valve opening and closing conditions are met, the valve can automatically open and close in two stages: fast closing and slow closing (specified and agreed upon in the order) according to the pre-set time and angle; And it can achieve a manual switch valve without electricity, effectively eliminating the destructive dynamic pressure hammer of the medium in the pipeline, preventing pipeline accidents, reducing pressure fluctuations in the pipeline system, and ensuring the safe and reliable operation of equipment. 4. The sealing surface of the main valve is made of metal hard seal or fluorine rubber nylon sealing structure, which is easy to open and close and reliable in sealing; Valves have good self closing and self sealing performance. The valve is designed and manufactured with a full bore design, and the flow resistance coefficient is only zero, which is unmatched by other types of valves.
