From March 18 to 20, 2026, the China Petroleum and Chemical Enterprise Procurement and Supply Chain Academic Exchange Conference was held at the National Exhibition and Convention Center in Tianjin, focusing on green and low-carbon transformation, intelligent and digital upgrading, and innovation in the coal chemical industry. Sufa Technology Innovation Co., Ltd. (SUFA) exhibited its high-end coal chemical valves and exchanged views with industry users on domestic substitution under severe operating conditions.
Why Coal Chemical Valves Are So Difficult to Make
As an important track for deep coal processing, the coal chemical industry faces extreme conditions of high temperature, high pressure, strong corrosion, and slurry containing solid impurities. Core control valves in this field have long relied on imports, with high procurement costs, long delivery cycles, and inconvenient after-sales response. To support the safe and stable operation of coal chemical plants, valves must offer superior wear resistance, sealing performance, and service life.
The two flagship products on display—the high-temperature high-pressure multi-channel slurry plunger valve and the coal direct liquefaction hot high-pressure separator level control valve—were both customized for coal chemical extremes. They feature specialized designs addressing common problems of conventional valves, such as wear, seal failure, and short service life, and can meet the demanding requirements of the entire coal chemical production process.
Core Product Listed in the National First (Set) Catalog
Notably, SUFA's independently developed coal direct liquefaction high-temperature high-pressure material distribution plunger valve was included in the fourth batch of the National Energy Administration's catalog of major technical equipment (first [set]) in the energy sector. Designed specifically for coal direct liquefaction units, the valve adopts a one-inlet four-outlet structure. The R&D team optimized structural strength, fluid erosion resistance, and fatigue resistance through simulation software, achieving independent breakthroughs in valve body material selection, surface hardening processes, sealing structure, and flow channel design—with a 100% localization rate for the complete machine and core components.
During the exhibition, SUFA's technical and commercial teams presented product application cases and selection essentials on site, and held discussions with participating enterprises on industry chain collaboration and supply-demand matching. For enterprises using coal chemical valves, choosing domestic equipment with a proven track record can secure plant operation while reducing procurement and maintenance costs.
