Aavolyn # 56-21054-046, AVA5015 TY210 Radial/Tangent Packing Ring
|
|
|
|
|
|
Single acting radial-tangent pairs consist of a radial load ring and a tangent sealing ring. The pair act together as a seal in one direction. The Type 210 are installed in combinations depending on the discharge pressure. They keep the gas from leaking from the cylinder to atmosphere. The radial ring is pinned to the tangent or sealing ring to prevent gas from leaking at the tangent joint. The pair of rings seal at the bore and against the back side. To obtain an effective seal the finish and parallelism of the faces are critical. Proper side clearance is required for the packing to function at operating temperatures and not be restricted in the packing case groove.

Material Description
|
|
- 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.
