We are loyal exhibitors of multinational exhibitions. Since 1994, we have become a substitute for imported products in the fields of refining catalysis and sulfur recovery, such as pneumatic triple-eccentric high-performance butterfly valves, high-performance jacketed butterfly valves, etc. At present, most of the refining catalytic butterfly valves and sulfur recovery jacket butterfly valves of large enterprises such as Sinopec and PetroChina use domestic valves. More than 70% of PetroChina and more than 90% of Sinopec use Zhongde products. In the early stage of localization, it was difficult. After nearly ten years of promotion, trial, and trust in receiving goods, the Sino-German brand has now been widely recognized, and users can use it with confidence. Refining enterprises are flammable and explosive enterprises. The fires that have occurred frequently over the years have caused huge casualties and economic losses. In particular, the fire protection of liquefied hydrocarbon spherical tanks is facing huge problems. The emergency shut-off ball valve for liquefied hydrocarbon spherical tanks jointly developed by Zhongde, SEI and Shijiazhuang Refinery, commonly known as the tank root valve, has begun to replace imports and be applied to refining and chemical enterprises. This product is based on the digestion of advanced European and American technologies, and is the only high-end product in the world that is independently developed and suitable for China's actual process requirements. It has been included in the mandatory use of PetroChina and Sinopec. In a high temperature environment of 1096 degrees, the valve can be opened and closed freely within half an hour. Once a fire occurs, there is a chance to control it. It can be closed to prevent the spherical tank from leaking. You can also open the valve to inject water into the tank to extinguish the fire in time to reduce oil leakage. , The fire aggravates the danger, eliminates safety hazards, and greatly improves the safety factor.

We also have a wholly-owned subsidiary, Shanghai Qingye Engineering Technology Co., Ltd., which develops application system software to effectively control various equipment such as control valves, flow meters, compressors, etc., which can reduce costs, optimize operations, save energy, environmental protection, and improve safety. The products include the torch integrated system FCS, the tank farm monitoring and management system, the oil product online reconciliation and optimization system, etc. The oil product loading system has obtained national patents. Light leaf makes our product structure more abundant and perfect.

We started to make control valves in 1992 and experienced ups and downs. We cherish the present and always maintain a sense of crisis. The future vision is to "be a century-old national brand and build the world's top control valve". This requires us to keep our feet on the ground and accumulate bit by bit. We must gather talents, create a superior corporate culture, improve management, improve the quality of sales and service personnel, and provide users with high-quality products and services. We have set up offices throughout the country and established a complete marketing and after-sales service network. Maintenance personnel must arrive at various sites across the country within 24 hours. When users think of Sino-German, they have a safe and reliable first-class brand image in their minds. We must advance in all directions, increase our influence, and expand our visibility. We will never be greedy for immediate benefits, we must have a long-term vision and win the permanent trust of users. For example, if users urgently need to replace domestically made parts of foreign brands, then we can supply them at the ex-factory price without increasing the price. In short, we must create an intangible and immeasurable brand image from all levels.
