Material selection requirements for the valve fitting Dec 29, 2018

Valve fittings include many types, usually small parts, such as valve bodies, valve covers, opening and closing parts, valve stems, brackets, etc., which are the main parts of the valve. These valve fittings tend to withstand the pressure of the medium directly, so the materials used must comply with the pressure and temperature rating of the valve.

 

In addition to these main parts, common valve accessories include seals, handles, wrenches, bearing glands, stem nuts, bushings, seals, gaskets, split rings, packing rings, nuts , bolts and screw plugs, etc. At present, there are many materials for manufacturing valve parts, including various grades of ferrous and non-ferrous metals and their alloys, and various non-metallic materials.

 

When selecting valve fitting materials, the main considerations include:

1.The pressure, temperature and characteristics of the working medium;

2. The force of the part and its function in the valve structure;

3. Good process.

4, under the above conditions, there must be lower costs.www.dmgcastings.com
