Ⅱ Advanced CNC machining centers, professional process ce... Ball check valves contain a ball that sits on the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole (seat). When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. But once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow. The ball moves up and down inside the valve depending on the flow and seals against the machined seat when no flow or reverse flow occurs and seals against the seat to stop the reverse flow. Ball check valves are typically preferred for use in pumping stations as they are self-cleaning as the ball rotates during the operation and are vertically maintenance-free.

It is a one-way valve installed at the outlet of a riverside drainage pipe. When the river tide level is higher than the outlet, and the pressure is greater than the pressure inside the pipe, the flap automatically closes to prevent the river tide from backing up into the drainage pipe. When the pressure inside the pipe is greater than the pressure outside of the flap then it opens and the medium inside the pipe is discharged, when the pressure from the drainage is released it will close.

Ⅱ Advanced CNC machining centers, professional process ce... Ball check valves contain a ball that sits on the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole (seat). When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. But once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow. The ball moves up and down inside the valve depending on the flow and seals against the machined seat when no flow or reverse flow occurs and seals against the seat to stop the reverse flow. Ball check valves are typically preferred for use in pumping stations as they are self-cleaning as the ball rotates during the operation and are vertically maintenance-free.

Ⅱ Advanced CNC machining centers, professional process ce... Ball check valves contain a ball that sits on the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole (seat). When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. But once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow. The ball moves up and down inside the valve depending on the flow and seals against the machined seat when no flow or reverse flow occurs and seals against the seat to stop the reverse flow. Ball check valves are typically preferred for use in pumping stations as they are self-cleaning as the ball rotates during the operation and are vertically maintenance-free.

Selecting an inappropriate valve construction may result in premature seat wear, leakage, or excessive actuator loading. The following technical factors should be considered when selecting butterfly valves for large-diameter water pipelines. 1. Valve structure: eccentric and concentric design For large diameter applications, valve construction directly affects seal life and torque per... ## Double Eccentric vs Concentric Butterfly Valve: Which Is Better for Water Transmission? (2026-01-28) **Category:** RKSfluid INDUSTRY NEWS **URL:** https://www.chinavalvesmanufacturer.com/news/Double-Eccentric-vs-Concentric-Butterfly-Valve-Which-Is-Better-for-Water-Transmission.html In water transmission and wastewater treatment projects, butterfly valves are widely used for flow isolation and regulation. However, selecting the right valve design—especially between concentric and double eccentric butterfly valves—directly affects sealing performance, service life, and long-term maintenance cost. Structural Difference: Why Eccentric Design Matters？ A concentric butterfly valve places the disc and shaft on the same centerline as the pipeline. While this design is simple, the disc remains in continuous contact with the seat during opening and closing, which leads to higher f... ## Why Dismantling Joints Are Essential for Valve Installation and Maintenance in Water Pipelines (2026-01-22) **Category:** RKSfluid INDUSTRY NEWS **URL:** https://www.chinavalvesmanufacturer.com/news/Why-Dismantling-Joints-Are-Essential-for-Valve-Installation-and-Maintenance-in-Water-Pipelines.html In water transmission and wastewater pipeline projects, valves are among the most critical components of the system. While considerable attention is usually given to valve selection, installation and future maintenance requirements are often underestimated during the design stage. In practice, many on-site difficulties are not caused by the valve itself, but by insufficient installation tolerance and limited maintenance accessibility. This is why dismantling joints are widely used in water pipeline systems, particularly in combination with large-diameter valves such as butterfly valves, gate v... ## Why Double Eccentric Butterfly Valves Are Widely Used in Water Transmission Pipelines (2026-01-15) **Category:** RKSfluid INDUSTRY NEWS **URL:** https://www.chinavalvesmanufacturer.com/news/Why-Double-Eccentric-Butterfly-Valves-Are-Widely-Used-in-Water-Transmission-Pipelines.html Water transmission pipelines are typically designed for long-distance, high-capacity operation under relatively stable pressure conditions. Compared with internal process pipelines, these systems place greater emphasis on valve reliability, sealing stability, and long-term maintenance performance. As pipeline diameters increase, valve selection becomes a key factor affecting system efficiency and operational continuity. In this context, double eccentric butterfly valves are widely applied in water transmission and wastewater systems, particularly in large-diameter pipelines. Their adoption is ... ## Pig Launcher and Receiver Solutions for Safe and Efficient Pipeline Pigging (2025-12-24) **Category:** RKSfluid INDUSTRY NEWS **URL:** https://www.chinavalvesmanufacturer.com/news/Pig-Launcher-and-Receiver-Solutions-for-Safe-and-Efficient-Pipeline-Pigging.html As pipeline systems continue to expand in scale and complexity, ensuring operational safety, efficiency, and long-term reliability has become a critical concern for operators.
