Valve Parts Introduction

Lined Valve The main parts include valve body, valve cover, opening and closing parts (such as gate, ball, valve disc, butterfly plate, valve plate, plug, etc.), valve stem, bracket, drive device, etc., which directly bear the medium pressure, and the materials used must comply with the provisions of "pressure and temperature grade of valve".

Commonly used valve parts include sealing rings, handles, valve stem nuts, wrenches, bearing glands, bushings, gaskets, seals, split rings, packing rings, nuts, bolts and screw plugs, etc.

Material of main valve parts There are many materials for manufacturing valve parts, including various grades of ferrous metals and non-ferrous metals and their alloys, various non-metallic materials, etc.

The materials for manufacturing valve parts should be selected according to the following factors: 1. The pressure, temperature and characteristics of the working medium. 2. The stress of the part and its role in the valve structure. 3. Good processability. 4. Under the above conditions, it should have a lower cost.
