The slab gate valve is a key component in pipeline transportation systems. With a flat gate design, it features a simple yet strong structure for effective medium interception. The valve seat offers excellent sealing for zero leakage, suitable for natural gas, oil, water, and other complex conditions. Its low friction between gate and seat ensures easy operation and long service life. Versatile installation methods adapt to different pipeline layouts. Widely used in energy, chemical, water supply/drainage industries for long-distance pipelines and industrial systems, it guarantees safe operation with stable reliability.
