PEEK Compressor Valves

 

The efficiency and reliability of reciprocating compressors can be significantly improved by using valve plates made of PEEK. In natural gas compressors, valve plates made of PEEK 5600GF30 can work continuously for up to 12 months, whereas steel plates usually break after about a month.

 

In the complex structure of a reciprocating compressor, the valve plate undoubtedly plays a crucial role as the “heart” of the compressor, directly affecting its efficiency and reliability. When using steel (which has a significantly shorter service life), if a valve disc breaks, the steel fragments can cause serious damage to the cylinder, piston and piston rings. The use of PEEK valve discs will prevent the future loss of such assets and significantly increase the added value for end-users such as the oil and gas industry or fertilizer producers by reducing downtime and associated costs.

 

In addition to a significantly longer service life, PEEK discs save energy during the opening and closing process. This is due to better wear characteristics, surface fit, elasticity and sealing, which reduces airflow losses. These polymer discs also produce less noise than steel.

 

Compressor plastic valve plate is based on polyether ether ketone (PEEK) as the base material, according to the user's needs to fill in a variety of auxiliary materials by granulation, injection molding, machining, with nine advantages:

 

1, high temperature resistance: PEEK long-term use temperature of 260 ℃, the normal working temperature of the valve plate can reach 200 ℃ or more.

 

2, high-pressure resistance (differential pressure): the valve piece working differential pressure of up to 15MPa or more.

 

3, high abrasion resistance: plastic valve sheet density is small, the same volume of light weight, in the reciprocating compressor operating conditions, the impact force is reduced, the resulting fatigue damage is reduced, the valve life is extended.

 

4, strong corrosion resistance: resistance to all media except oxygen, chlorine and concentrated sulfuric acid.

 

5, low noise: can absorb part of the impact energy to reduce noise.

 

6, good sealing, high efficiency: PEEK valve sheet in the operating temperature, the sealing surface has a self-adjusting function, can be automatically completed within 24 hours and the contact surface shape of the fine-tuning, so that the sealing effect is optimal, the shortest possible time compressor to achieve high compression efficiency.

 

7, low energy consumption: with the improvement of sealing, the compressor's power consumption and temperature rise synchronized to reduce the energy consumption of the compressor compared with the metal valve plate using plastic valve plate can be reduced by 5% -10%.

 

8, high security: valve plate toughness, not easy to break, even if the valve plate breaks into the cylinder will not cause damage to the cylinder or produce sparks. PEEK oxygen index is high, in the flammable gases as the medium of the compressor conditions, the plastic valve plate has a higher level of security.

 

9, good hydrolysis resistance: PEEK valve plate is not affected by water and high pressure water vapor.

 

In fact, PEEK as a metal replacement material has been successfully used in various industries for more than 18 years, including automotive, aviation, oil and gas industries. This is due to Junghua's long experience in the field and the fact that PEEK combines a variety of excellent properties that predestine it to replace metal materials in extreme environmental conditions. These properties include high temperature resistance, high wear resistance, high impact strength, excellent chemical resistance, hydrolysis resistance and dimensional stability.

 

As a key component of the compressor, PEEK material valve plate, its market scale is expanding, the demand continues to grow, the competitive landscape is becoming increasingly fierce, and the development trend is characterized by high performance, customization, green environmental protection and intelligent manufacturing.

 

 

 

PEEK valve plate in petrochemical applications

 

Valve seals

 

PEEK valve plate as a valve seal, can provide reliable sealing performance, to prevent fluid leakage. Its excellent chemical stability and high temperature resistance make it adaptable to a variety of harsh operating environments, ensuring the safe operation of the valve.

 

Compared with traditional sealing materials, PEEK spools have a longer service life and lower maintenance costs, bringing significant economic benefits to petrochemical companies.

 

Control valve components

 

Control valves play a critical role in petrochemical production processes, and PEEK valve discs can be used in key components such as spools and seats to improve the performance and reliability of control valves.

 

The high precision and good abrasion resistance of PEEK spools can ensure precise control of control valves, reduce errors and improve production efficiency. At the same time, its high temperature and corrosion resistance can ensure the long-term stable operation of control valves in harsh environments.

 

Pump and Valve Accessories

 

Pumps and valves in the petrochemical industry require frequent replacement of fittings to ensure the normal operation of the equipment, PEEK valves as pump and valve fittings, with good wear resistance and corrosion resistance, can extend the service life of the fittings and reduce the maintenance costs of the equipment.
