Microfinish make butterfly, ball and gate valve distributor in India

Microfinish Valve is a branded valve produced by the known manufacturer Microfinish. Since the brand is known and the valves are of high quality, there is a market demand for the branded valves. The valves come in different types, shapes, material grades and functionalities. The Microfinish Trunnion Mounted Ball Valve is a ball valve with a ball inside the valve body used to regulate the liquid flow while the ball is mounted on a trunnion. This allows for the valve to open and close precisely, making the valve performance more accurate. There are other types of valves but the Microfinish Mounted Ball Valve is effective in specific applications such as the petroleum, petrochemical and in the oil and gas industrial applications.

The Microfinish Two Piece Trunnion Mounted Ball Valve is made up of different material grades such as cast iron, carbon steel, ductile iron, duplex steel, alloy materials and many others. The selection of materials depends on the nature of the application, the liquid that is to flow through the valve and the application conditions. Depending on the operating temperatures required by the application, the Microfinish Cryogenic valves can also work under cryogenic temperatures as well as elevated temperatures. The valve sizes, dimensions and pressure capacities vary according to the material grades and the valve standard specifications.
