ASME SA 351 grade CF8m ball valve, Gate and Check Valves manufacturer in India
astm a351 gr. cf8m Valves have up to 21% chromium and 8% nickel in their chemical composition with carbon, manganese, silicon, sulfur, phosphorus and molybdenum in the composition. The material also has 485MPa minimum tensile strength, 275MPa minimum yield strength and up to 207 HB max harness. The astm a351 gr. cf8m Ball Valves are one type of valves in this grade of material. The valves can be ball valves, gate valves, globe valves and other types based on the structure. There are also functional differences in the valves such as the check valve, control valve and the safety valves. The astm a351 gr cf8m stainless steel Gate Valves use a gate to open and close the valve.

These gate valves reduce the water hammer effect as they are opened and closed by the rotation of a stem and the operation is comparatively slow. The aço inox astm a351 gr cf8m Globe Valves are gate valves with the gates in a globular disc shape and an opening parallel to the axis of the fluid flow.
Table of Content
There are other types and shapes of the gate valves such as the stainless steel a351 gr. cf8m Butterfly Valves. The butterfly valves have the disc in the shape of a butterfly with the central axis connected to the handle. The application of these valves can be seen in the water, waste water, petroleum, oil and gas and in the food processing sectors.
