SAPAG butterfly valves are used to regulate or isolate the flow of liquids and gases in various industrial applications. They are commonly found in water treatment plants, chemical processing, oil and gas industries, and HVAC systems.

SAPAG butterfly valves work by rotating a disc within the valve body to control the flow. The disc is positioned in the center of the pipe, and when the valve is fully closed, the disc blocks the flow. When the valve is open, the disc turns to allow the flow to pass through.

SAPAG butterfly valves are made from a variety of materials including cast iron, stainless steel, ductile iron, and PVC. The choice of material depends on the specific application and the type of fluid being controlled.

SAPAG butterfly valves come in a wide range of sizes, typically from 2 inches to 48 inches in diameter. This variety allows them to be used in many different piping systems, from small to large-scale operations.

To install a SAPAG butterfly valve, first ensure the pipeline is clean and free from debris. Position the valve between the flanges, ensuring the disc is in the partially open position to avoid damaging the seal. Secure the valve with appropriate flange bolts and tighten evenly.

Maintenance for SAPAG butterfly valves includes regular inspection for leaks, ensuring the disc and seat are clean, lubricating moving parts, and checking for any signs of wear or corrosion. Routine maintenance helps ensure optimal performance and longevity.
