Special material valves refer to valves made of special materials to meet the characteristics of high temperature resistance, corrosion resistance, wear resistance, and other working conditions. Due to the important role played by valves in the industrial field, the selection of valve materials directly affects the service life and normal operation of valves. There are various types of special material valves, classified by material of valve body:

(1) Non metallic material valves such as ceramic valves, fiberglass valves and plastic valves.

(2) Metal material valves such as copper alloy valves, aluminum alloy valves, lead alloy valves, Monel alloy valves, low alloy steel valves, and high alloy steel valves.

(3) Metal body lined valves such as lead lined valves, plastic lined valves, and enamel lined valves.

The special valves produced by BOLON are made of metal materials. Classified by purpose and function as follows:

(1) Used to cut off or connect media flow. Including gate valves, globe valves, diaphragm valves, ball valves, plug valves, butterfly valves, plunger valves, ball plug valves, needle instrument valves, etc.

(2) Used to regulate the flow rate, pressure, etc. of the medium. Including regulating valves, throttle valves, pressure reducing valves, etc.

(3) Used to prevent media to be back. Including check valves of various structures.

(4)Used for separating, distributing, or mixing media. Including distribution valves and drain valves of various structures.

How to choose the appropriate valve material

Choosing suitable valve materials requires consideration of various factors such as operating environment, working medium, operating temperature, and pressure. Generally speaking, when selecting valve specialty materials, the following points should be noted:

1. Selection based on working medium: Different valve materials can withstand different media, and corresponding materials need to be selected according to the properties of the media.

2. Selection based on working temperature and pressure: It is necessary to select valve materials based on factors such as working temperature and pressure to ensure that the valve can work normally.

3. Considering economic factors: Different valve specialty materials have different prices, and it is necessary to comprehensively consider economic factors to choose appropriate materials.

Precautions for using valve special materials

1. When using, it is necessary to avoid load impact and vibration, and to avoid collisions on the surface of the material;

2. Standard operating procedures should be followed during maintenance and upkeep to avoid the use of corrosive media such as acids and alkalis;

3. Before using valve special materials, comprehensive inspection and quality testing are required to ensure that the materials meet the requirements;

4. During use, it is necessary to regularly check the status and effectiveness of valve special materials.

Valve specialty materials are crucial for maintaining normal valve operation, and selecting the appropriate valve specialty materials is crucial for improving valve service life and safety. When using valve special materials, it is necessary to pay attention to safe operation and reasonable maintenance.

BOLON alloy materials include duplex stainless steel, super duplex stainless steel, alloy 20, Monel alloy, Hastelloy alloy, chromium cobalt alloy, pure titanium, titanium alloy, 904L, zirconium, uranium, 254 SMO, 6Moly (6Mo), nickel, etc.. We welcome end users and engineering companies, especially chemical, plastic, and polymer manufacturers, fine chemical manufacturers, petrochemical and natural gas derived generators, as well as nuclear facility operators and naval, submarine, and marine equipment manufacturers, to inquire by phone or email.
