What kind of Peek material valve should be chosen in different industries? ——Peek valve disc material selection guide

Do you want to know which Peek material can meet the requirements, whether to choose Peek resin or modified PEEK material? I hope the following article can help you

Chemical industry:

-Corrosive medium environment:

 Pure PEEK material can be used, which has excellent resistance to almost all common chemicals. In some pipelines and valves that transport corrosive liquids such as acids and bases, pure PEEK valve plates can work stably for a long time and are not easily corroded.

-High temperature and high pressure with wear:

 Carbon fiber reinforced PEEK composite material, such as PEEK-PRESCF30, is used. Carbon fiber reinforced PEEK composite materials can improve the hardness, rigidity, and dimensional stability of valves for hydrogen compressors and petroleum gas compressors on large petrochemical production lines, and can withstand high temperatures, high pressures, and frequent friction.

Electronic and electrical industry:

-An anti-static environment is required:

 Conductive grade PEEK is a suitable choice as it enhances conductivity by adding carbon fiber. For example, in the manufacturing of electronic devices, the use of conductive grade PEEK for valve plates in small electronic component production equipment that is sensitive to static electricity can prevent the accumulation of static electricity and damage to the components.

-Scenario with high insulation requirements: 

Basic grade PEEK is sufficient to meet the requirements. It is an ideal electrical insulator that can maintain good electrical insulation performance under harsh working conditions such as high temperature, high voltage, and high humidity. It can be used for the production of some electronic insulation membranes and valve plates.

Refrigeration industry:

In the air valve of refrigeration compressors, considering the high pressure, high temperature, and corrosive environment in which the valve plate is located, PEEK composite materials reinforced with fiberglass or carbon fiber, such as PEEK5600CF30 or PEEK5600GF30, can be selected to better adapt to this environment, ensure long-term stable operation of the compressor, have high fatigue strength, low density, and reduce power consumption and braking noise.

Mechanical transmission industry

for valve plates in mechanical components that require low friction and high wear resistance, such as sliding bearings, seals, etc., sliding grade PEEK materials with added graphite, polytetrafluoroethylene (PTFE), etc. can be used to reduce the friction coefficient, improve wear resistance and fatigue resistance.
