PEEK Valve Seat

PEEK Valve Seat is one of the most efficient valve components produced from PEEK which is short for poly ether ether ketone. The commonly used material for valve seats is PEEK mainly due to its high temperature and corrosion-resistant nature.
Characterized with a melting point of 334°C and glass transition temperature of 143°C, PEEK valve plates for compressors can perform stably and steadily in high temperature and pressure conditions.

PEEK Valve Plate

PEEK valve plates for compressors are most suitable for pump compressor valve plates and other high temperature valve seats in nuclear power, petroleum and chemical industries.

valve seats grade & application

valve plate PEEK
  1. Aerospace: Aerospace is one of the fields in which the heat and pressure resistance of PEEK valve plate have particular value. It plays a crucial role in ensuring the reliability of fuel and hydraulic systems necessary for safety and effectiveness in operating machinery.
  2. Oil and Gas: That is why the oil and gas industry is faced quite often with corrosion problems. Due to its excellent chemical compatibility and low moisture-absorbing characteristics, Virgin PEEK valve plate can be used in valve seats exposed to high-pressure pipeline systems to prevent leakage and valve failures.
  1. High-Performance Motors: In racing engines, every gram of weight and degree of heat accounts, and hence carbon fiber reinforced PEEK valve plate offers the right amount of strength and stiffness needed without adding much bulk. This material can withstand the conditions that are inherent in high-performance motors.
  2. Industrial Pumps: When it comes to aggressive fluids, carbon fiber-reinforced PEEK valve plate stands as the best solution due to the high wear and thermal stability of the material and this means that maintenance and replacement are less frequent.
  1. Chemical Processing: For chemical processing applications, however, glass fiber-reinforced PEEK valve plate is the best as it offers better compression resistance and less shrinkage. This makes it operate under high static loads and extreme temperatures, which are normally found in reactors and separators' operating conditions.
  2. Pharmaceuticals: Also, materials used for the production of products within the pharmaceutical industry should withstand functional and cleaning processes and, at the same time, retain their dimensions. Glass fiber reinforced PEEK valve plate has such improved characteristics, and therefore, it provides safety and reliability in a sterile environment.

Advantages of PEEK Valve seat

High-temperature stability

PEEK Valve seat can sustain its strength in an environment up to 260°C which is ideal for controlling high-temperature fluids.

Chemical resistance

It was also observed that PEEK Valve seat has an excellent resistance to many chemicals. It can be used for a long time in corrosive areas without affecting the valve's reliability and safety

Mechanical strength

PEEK Valve seat has high levels of strength and stiffness which are further comparable to metal materials; the material can handle high loads and alternating stresses leading to increased service life

Dimensional stability

It has relatively high thermal stability and a low coefficient of thermal expansion, the dimensional stability of PEEK Valve seat is good when used in applications involving exposure to changes in temperature and humidity

Flame retardant performance

From the UL94 V-0 rating, it is evident that PEEK Valve seat has improved on its heat resistance; this material does not ignite aself-extinguishhes hence enhancing safety in sensitive applications

  1. It is necessary to ensure that the Plate Valve Compressor and the disc surfaces that are to be mated together are clean and free from mold and any other form of damage.
  2. Insert the Plate Valve Compressor and the disc properly in the valve body as recommended by the valve seat manufacturer.
  3. Make sure that they are to be aligned correctly and they do not have any kind of twist on them.
  4. Install the seat and disc using the recommended installation tools and allow an even force of torque to be exerted to fix the components securely. However, over tighten the screw may cause damage to the PEEK Plate Valve Compressor.
  5. Make sure that the valve is fully opened and closed without any problem of sticking. If larger than normal, then check the installation position and torque of the bolted joint.
  6. Some staff test the leakage of the valve seat before they put it into use, to guarantee that the sealing performance of the valve plate has met the requirement.

  1. Check the valve plate carefully to ascertain that none of the following are present; cracks, deformation, and any other signs that may reveal that the valve plate is not functioning in the best way.
  2. Make sure that the valve operates normally and is not jammed or whistling during the opening and closing processes.
  3. If leakage exists, another check should be made with the seat and the disc if they are properly installed and if not, the proper position should be adjusted. When it cannot be solved, try to change the compressor valve plate and/or the disc.
  4. When replacing the seat and disc, the PEEK compressor valve plate products must be of the same quality or they must have the same performance as the raw material. Certain sorts of composite arrangements could jeopardize the sealing capacity in some way.
  5. To increase the service life it is necessary to clean the valve plate and free it from the scale and other contaminants. They can with a neutral detergent using a soft cloth to clean them.
  6. In high temperatures and severe corrosive medium, it is advisable to reduce the inspection period to enhance the performance of the valve plate.
