Cast Iron Valves

• Material: Cast iron body, generally suitable for water and other non-corrosive fluids.

• Function: Prevents backflow and protects pumps and pipelines from reverse-flow damage.

• Operation: Opens automatically when the fluid flows in the forward direction and closes when the flow reverses.

• Connection: Commonly supplied with flanged ends for pipeline installation.

• Applications: Water pumping stations, irrigation systems, municipal water supply, sewage/drainage systems, and industrial pipelines.

• Advantages: Robust construction, simple operation, low maintenance, and reliable backflow prevention.

Robust Hydraulic Operation

Our reflux valves operate using efficient hydraulic mechanisms to ensure minimal friction and superior performance during water flow regulation. The design offers consistent reliability for medium pressure systems, reducing the likelihood of mechanical failure or leakage.


Customizable Sizing and Standard Quality

These valves come in a variety of sizes, with a standard port size of 100 mm to suit diverse water system requirements. Each valve is manufactured with precise dimensions and weights depending on size, meeting industry standards for water applications.


Durable Cast Iron Construction

Constructed from premium cast iron, our reflux valves resist wear and corrosion. This robust material selection guarantees longevity and consistent operation, even under challenging water conditions or frequent cycling in municipal systems.

• Unidirectional Flow: The valve automatically opens via water pressure in the intended direction and snaps shut via gravity or back-pressure if the flow reverses.
• Passive Operation: It functions entirely on fluid dynamics, requiring zero electrical power or manual intervention to operate.
• Pump Protection: By blocking backflow, it shields expensive agricultural surface pumps and submersible borewells from sudden hydraulic shock (water hammer) and reverse rotation

Rugged Construction and Reliable Performance

Designed with high-grade cast iron, this check valve ensures longevity and consistent operation, even under medium pressure. Its internal structure prevents water reversal, preserving the system's integrity and preventing contamination. The sky blue coating adds corrosion resistance, making this valve a dependable choice in water management for diverse environments.


Versatile Sizing for Wide Application

Whether your system requires compact 15 mm valves or larger 50 mm options, this check valve accommodates a variety of set-ups. The choice of sizes and customizable length, width, and weight ensure compatibility across different water distribution and hydraulic applications, fitting both commercial and municipal infrastructures.
