Buy ASTM A351 CF8 Centerline Rs Butterfly Valves online at best price in India

Flange Center Line Butterfly Valve is a gate valve that has different modifications. The gate is in the shape of a disc that is attached to a centered axis. The look resembles a butterfly. The centerline design allows for the control of the fluid flow. The Center Line Resilient Seated Butterfly Valves have one handle or actuator, stem, body, resilient seat, butterfly disc and the end packaging. The flanged valves also have flanged endings. These are to be connected to the flanged end pipes. There are different design variations in the valves such as the Single Type Flange Center Line Butterfly Valve and others.

The valve body is often made up of cast iron or ductile iron. The disc is made of stainless steel or ductile iron. The stem is of stainless steel. The Centerline Butterfly Valve can have the seat in EPDM, NBR, VITON or PTFE material. There are different standards for the face to face connections, the flange ends and the test types. The face to face can be of ANSI B16.1, the flange end of ANSI B16.5 and the tests vary according to the API 598 standards. The Ductile iron Center Line Butterfly Valve can vary in size and dimensions according to these standards. The pressure capacities also differ with the standards.
