In harsh industrial scenarios such as petrochemicals, natural gas transmission, and chemical pharmaceutical manufacturing, the precise shut-off, regulation, and sealing performance of fluids directly determine the safety and operational efficiency of the entire system. OUWEI, deeply engaged in valve R&D and manufacturing, has launched a series of plug valves driven by technological innovation, which have become the "reliable valve core" for complex working conditions and safeguarded industrial fluid control with their outstanding sealing performance, wear resistance, and adaptability.
OUWEI plug valves adopt an integrated plug core design. The valve core and valve seat are precisely lapped to form a metal-to-metal hard-sealed structure, with the sealing surface hardness reaching above HRC70. This effectively resists medium scouring, corrosion, and wear, achieving a sealing grade above Class V and eliminating leakage risks. Even under high-pressure, high-temperature, and particle-containing medium conditions, the valves can maintain long-term stable sealing performance.
The product features a compact structure and convenient, efficient operation: it adopts a straight-through flow channel design with a flow resistance coefficient as low as 0.08, ensuring smooth medium circulation without stagnant dead corners and greatly improving transmission efficiency. The valve stem and plug core are connected integrally for precise transmission, and full opening/closing can be achieved with only a 90° rotation, requiring low opening and closing torque. It is compatible with various drive modes such as manual, pneumatic, and electric, meeting the needs of automated control and remote operation and adapting to the control habits of different industrial scenarios.
From the shut-off control of long-distance natural gas pipelines, to the material regulation of chemical reactors, and the on-off switching of steam systems, OUWEI plug valves are suitable for harsh working conditions in multiple industries with core advantages including a wide temperature resistance range (-60℃~600℃), high pressure rating (Class 150~Class 3000), and long service life (over 150,000 trouble-free opening and closing cycles). Meanwhile, the products support modular design and customized production, and the valve core material and sealing structure can be optimized according to medium characteristics and working condition parameters to fully meet customers' personalized needs.
As a core component of industrial fluid control, OUWEI plug valves break the adaptation limitations of traditional plug valves with their product traits of "robust sealing, efficient on-off control, and stable reliability", helping enterprises improve production efficiency, reduce operation and maintenance costs, and demonstrate the professional strength and technical confidence of Chinese intelligent manufacturing in the valve field.
