Flange wafer check valves, also known as wafer check valves, are flow control devices that are commonly used to regulate the flow of fluids in pipelines. These valves are designed to be mounted between flanges in a reduced, lightweight form factor. They are primarily used to prevent backflow and to protect pumps and other equipment from damage.

Flange wafer check valves are available in a wide range of sizes, typically ranging from 2 inches to 48 inches in diameter. They are designed to handle a range of pressures, with maximum pressure ratings that can range from 150 to 2500 psi depending on the application.

Flange wafer check valves can be used in various applications such as water, oil and gas, petrochemical, pulp and paper, and other industries.These valves are constructed using a variety of materials, including cast iron, stainless steel, carbon steel, and other alloys depending on the required characteristics of the pipeline fluid, such as pH, temperature, pressure or chemical composition. The valve body is typically sandwiched between two flanges, which apply pressure to hold the valve securely in placeIn conclusion, flange wafer check valves are a versatile flow control solution that provide efficient flow regulation with minimal pressure drop. They are widely used in various industries, and their excellent design and material choices ensure a long service life and reliable performance.

Connecting end	ASME B16.5、ASME B16.47、
Test standard	API 598、ISO 5208
Operation method	The valve clack is automatically opened and closed under the medium force to prevent flowing to another direction.
Application fields	For application in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, etc.
Other remarks 1	Due to loading of spring, the valve clack can move flexibly without jamming, and has a good sealing performance.
Other remarks 2	Built-in pin roll, without external leakage point
Other remarks 3	Suitable for medium backflow prevention in pipeline or device
Other remarks 4	tShort closing travel of valve clack, and small impact at valve closing; short structural length, most suitable for positions with limited mounting spare
Other remarks 5	The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
