Ductile Rion Dual Check Valve with Non-Return Spring Type Double Disc Swing Check Valve
Available in ductile iron (robust, cost-effective) and stainless steel (corrosion-resistant), this double disc check valve suits diverse pressure scenarios. Its rubber seals enable tight backflow blocking, with temperature tolerance of -10°C to 90°C and reliable leak prevention. The dual-disc design ensures smooth fluid passage and minimal pressure drop, while inline mounting simplifies installation. Ideal for municipal water lines, industrial pipelines, and chemical transfer systems, complying with ISO 7126 standards for consistent performance.

product description
As a key fluid control device, the core function of a check valve is to ensure that the fluid can only flow in one direction.
The lift check valve is a common type. The disc moves up and down perpendicular to the direction of fluid flow. When the fluid flows forward, the disc is lifted up, enabling the fluid to pass. When the fluid flows in the reverse direction, the disc drops to close the passage under its own gravity.
The pilot - operated check valve uses a pilot system to control the opening and closing of the main disc. It can respond quickly under a small pressure difference to effectively control the fluid. This type of check valve is widely used in some occasions with high requirements for control accuracy.
Thanks to their unique functions, check valves play an indispensable role in many industrial processes, effectively avoiding various problems caused by fluid back - flow.
