Aavolyn # 20056-26003-012, AVA5015 TY260 PBU Packing Ring Set
The AVA-PBU pressure balanced unitized design is the latest concept in shaft seals. The AVA-PBU was developed to extend packing life in conventional applications. However, it has found use in all services from non-lube air to 50,000 PSI compressors handling polyethylene. Each ring operates on the principle of balancing the pressures around the seal to minimize the downward force of the piston rod. Frictional forces are reduced considerably. In applications where filled PTFE materials are utilized, there is less chance that the PV limit (temperature/pressure limit) of the PTFE will be exceeded because of reduced frictional heat.
Cylinder/ Rod Diameter
Throughout the Specialty Gas industry AVA5015, is recognized as the finest material available for use in Oxygen and Argon service. It was specifically developed for Oxygen bearing gases. No other product comes close to the wear properties exhibited by this patented PTFE blend. The proprietary fillers in AVA5015 form a surface film with excellent frictional characteristics. This film increases the life of the sealing ring three to five times that of other filled PTFE.
The specific percentage and type of filler, as well as particle size, molding procedures, and sintering cycles are critical to the development of the surface film.
When combined with the PBU pressure balanced piston ring & packing designs, AVA5015. significantly reduces surface generated frictional heat. Every major specialty gas manufacturer has verified the performance of this unique material over any products available on the market today. Specific application performance data can be obtained on request.
Substitute materials have been offered for use in Oxygen or Argon applications, resulting in reduced ring life. The glass/moly filled and straight glass filled PTFE exhibit 1/2 to 1/3 the seal life when substituted for the AAVOLYN product. Once the AVA5015 seals seat after installation, wear rates drop substantially. This proprietary material eliminates wear on the sealing surfaces such as piston grooves, cylinder walls and piston rods & limits ring wear.
Recommended Usage: Oxygen, Argon, Air Though out the Specialty Gas Industry AVA5015 is recognized as the finest material available for Oxygen service.
