A mud valve is a special-purpose valve designed specifically for conveying mud media containing a large number of solid particles and with high viscosity. Its core structure adopts wear-resistant and erosion-resistant valve cores and valve seats (usually made of wear-resistant alloys or rubber materials), and the valve body flow channel is designed as straight-through type to reduce medium retention and erosion wear.

Mostly adopting gate valve or ball valve structure, it controls mud transportation by opening and closing the gate plate or ball. It features strong wear resistance, reliable sealing and excellent anti-clogging performance.

Considering the special nature of mud media, some mud valves are also equipped with flushing ports to regularly flush the valve body cavity and prevent mud deposition and blockage.

Mainly applied in fields such as drilling operations, mining, sewage treatment and dredging projects, it serves as a core control and shut-off component in mud circulation systems and transmission pipelines, ensuring the stability and safety of solid-containing medium transportation.
