These NEW conversion kits are suitable for immediate installation in most
standard designs of flexing plate valves as used in most of the popular air
compressors with little or no modification required.
With high temperature PEEK (200oC) polymer plates installed both seat
wear and valve noise are reduced. (Lower valve plate weight results in reduced
valve plate momentum hence less wear.) Standard coil springs are replaced with
one spring plate (suction) and two spring plates (discharge). Broken coil
springs are totally eliminated. Polymer clip plate design does not require valve
seat profiling therefore extending the life of normally unserviceable valve
seats.
Design and manufacturing excellence are CPA Trademarks. Both are essential to
supply piston rings that are effective. We offer a comprehensive range of rings
and materials for all types of service. To design piston rings that will work successfully
in the petrochemical industry today, comprehension of the dynamics which occur
within process compressors must be firmly established. CPA's success within this
industry is testimony to it's qualifications. After careful analysis of
operating conditions and an assessment of compressor condition. CPA can then
design piston rings to suit your specific application. This will ensure that
optimum ring life will be obtained for all types of service.
These designs Installation of CPA rider rings will maintain cylinder bore condition
therefore enhancing piston ring performance. It is essential that rider rings
are installed on all reciprocating compressors where the full benefit of non-metallic is to be gained. Rider rings (generally manufactured from filled
PTFE) will support the piston and a proportion of the piston rod weight. This
virtually eliminates piston to cylinder scoring even in the event of temporary
lubrication failure. Filled PTE is fail safe unlike metallic components. CPA
offers many designs relevant to specific applications and improper selection
will inhabit piston ring performance. CPA will match piston and rider ring
design to suit your application.
