Product Description

Flow Coefficients(Cv Values)

Flow coefficientis an index to measure the flow capacity of valve. The more the flow coefficientis,the less the pressure lossupon fluid flowing through the valve. The values of flow coefficient differ from the sizes,types and structures of valves. Valves ofdifferent types and specifications should be separately teated to make certain of ist value of flow coefficient. For valves of thesame structure,the value of flow coefficient differs according to the directions of fluid through the valves. This diference is usu-ally caused by the difference in pressure recovery.

The table below is the flow coefficient of double eccentric butterfly valve,used for reference to choose valve flow coefficient.

Cv means the American gallons of +60 F (+16°C) water flowing through the valve per minute under 1 pound/inch 2 (0.003561424Mpa)pressure drop.

Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material

We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.

Forging & Casting

Advanced forging and casting processes are used to produce strong and reliable valve bodies and components. Strict process control ensures uniform structure, dimensional accuracy and excellent mechanical performance.

CNC Machining

Our CNC machining equipment provides precise and consistent processing of valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Shot Blasting & Coating

Valve surfaces are professionally shot blasted to remove rust, scale and impurities. Protective coatings are then applied according to customer requirements, providing excellent corrosion resistance and a durable surface finish.

Pressure Testing

Every valve undergoes strict pressure testing before shipment. Body and seat tests are performed according to applicable standards and customer specifications to verify pressure resistance and sealing reliability.

Quality Inspection

Our quality control team conducts comprehensive inspections throughout the production process. Finished valves are checked for dimensions, appearance, materials, pressure performance and overall quality before final approval and shipment.
