A plug valve is a type of valve widely used in industrial fluid control systems. Featuring a simple and robust design, it is particularly suitable for precise control over fluid direction and flow rate. The operating principle of a plug valve relies on a rotating “plug” to regulate fluid flow within

US Standards for Plug ValvesDesign and Manufacturing Standards• API 599: This standard specifies the design, materials, dimensions, and testing requirements for plug valves. It ensures that valves meet high standards for pressure containment, shutoff capability, and operational reliability.• ANSI B1

Excellent sealing performance. There is an oil groove between the valve body and the sealing surface. Sealing grease can be injected into the valve seat through the oil nozzle at any time to form an oil film seal and enhance the sealing performance. This unique sealing design ensures zero leakage of

Working principle of three-way cock valve: The three-way cock valve is a valve with three channels. It controls the flow direction of fluid by rotating the plug. Its main function is to realize the diversion, confluence or switching of the flow direction of fluid. The plug of the cock valve is usual
