The Kevlar woven bearing valve bushing, constructed from stainless steel 316, offers a robust and high-performance solution for various industrial applications. The combination of (Polytetrafluoroethylene) and Kevlar woven material creates a unique material with excellent chemical resistance, low friction, and high temperature tolerance.
The stainless steel 316 backing material provides superior corrosion resistance and durability, ensuring the bushing can withstand harsh environments and demanding operating conditions. The Kevlar woven reinforcement adds strength and rigidity to the layer, enhancing its mechanical properties and wear resistance.
This bearing valve bushing is designed to provide smooth and reliable operation in valves, pumps, and other fluid handling equipment. Its ability to handle high pressure, corrosive media, and extreme temperatures makes it an ideal choice for critical applications in industries such as petrochemical, chemical processing, and marine.
By combining the strengths of , Kevlar, and stainless steel 316, this valve bushing offers a long-lasting and dependable solution for maintaining the integrity and performance of fluid systems.
Kevlar reinforced high-performance material The valve bearing is a composite material of compounded tape on a metal shell. This material structure enables machining of the bearing in the housing--which is an alternative to the sizing process--to obtain tightest tolerances on the inside diameter.
The very thick layer isolates noise and allows to design bearings without play. Bearings of more than 0.75 mm thickness can be produced with an interference fit in the housing. Various methods are available to protect the steel shell from corrosion.
