In industrial fluid systems such as petrochemicals and energy power, the control of multi-path medium commutation, confluence and diversion has long relied on the linkage of multiple valve groups, which not only occupies a large amount of installation space, but also has industry pain points such as operational lag and numerous leakage points. OUWEI, a brand deeply engaged in valve R&D, has launched its X-type flow path 4-way ball valve, which realizes precise control of complex flow paths with an integrated structure, providing an efficient solution for industrial pipeline systems.
OUWEI 4-way ball valve adopts a three-body valve body + X-type orthogonal flow path ball design. The four through-holes are evenly distributed on the equatorial circumferential section of the ball and are precisely matched with the four connecting ports of the valve body. A 90° rotation can complete the synchronous switching of double flow paths, realizing the flow path conversion between A↔B/C↔D and A↔D/B↔C. It meets the core working conditions such as medium reversal in heat exchange systems and dual-loop backup switching. Compared with traditional multi-valve combination schemes, it can reduce more than 60% of pipeline connection points, significantly lowering construction costs and leakage risks.
The product has achieved technological breakthroughs in sealing and adaptability: the valve seat adopts a metal-nonmetal composite sealing structure. The soft-sealed version can reach ANSI Class VI bubble-tight sealing, while the hard-sealed model undergoes hard alloy surfacing treatment, with the sealing surface hardness reaching above HRC68, which can withstand pressure ratings from Class 150 to Class 2500 and a wide temperature range of -40℃~550℃. Meanwhile, it supports the integration of various drive devices such as handle, worm gear, pneumatic and electric actuators, and the valve position can be locked to prevent misoperation, adapting to the remote control needs of automated production lines.
From the multi-path feed blending of chemical reactors to the commutation of power plant circulating water systems, OUWEI 4-way ball valve has become a core component in the field of industrial fluid control with features such as low flow resistance (resistance coefficient ≤0.12), high opening and closing frequency (over 100,000 trouble-free operations) and modular maintenance, providing reliable support for various industries to achieve "one valve for multiple uses and intelligent flow control".
